Thank you so much for stressing the absolute importance of respiratory safety! I see so many videos made by people who are cavalier about the need to be safe using this stuff. Kudos to you!!!

[@katt7938]

Just like to say your an excellent teacher,clear concise,many thanks

[@rushiaj1222]

I’ve been trying my hand at dyeing yarn. I tried food coloring and I recently bought acid dyes. I was wondering how much to use for dye stock so I’m super excited about finding this series😁

[@artisticallybyamber35]

This series is a godsend!! Thank you so much for making the process seem a little less intimidating!

[@MamaMiety]

Thank you so much for the acid dye instructional series. I am a crocheter and hope to see more instructionals from you on hand dyed yarn.

[@barbaradunn104]

You are a very good, straightforward teacher. Thank you!

[@twistknit1]

I took a class at the Prochem company, but I haven't dyed yarn in a long while. This is just the real refresher course I needed!

[@knottywoodyarn9629]

Awesome! Glad to have you.

[@ooohlaa13]

very wonderfully clear, I have been trying to grasp this for a long time, thanx.

[@judithlimbrick3639]

Just found you, I am now hooked and will be binge watching Thank you for making this so easy to understand!

[@eneal2056]

This was an incredibly helpful tutorial on dyes. Thank you so much for clearing up the confusion left by other yarn dyeing videos.

[@Kittehz1]

So informative. I want to watch them all before I dive in!

[@knitordi]

Great explanation of percentages. I can't wait for the next tutorials. Thanks for the information.

[@jeanettewestover]

Wow right place right time. Thank you for this series.

[@sarahmoxley738]

His is seriously the best tutorial I have found. Thank you so much!

[@kristinascozycraftingcorne5227]

Thank you so much! I will be watching the rest!

[@knitpicksOfficial]

Nice explanation!

[@sheryloermann234]

Thank you SO much for clarifying the math for me!

[@hemmerable]

Amazing! thank you for explaining this so well. I understood exactly. I was struggling with conversion with the book i bought and the materials I purchased.

[@jammiegoodwin]

Very simple and helpful, thank you!

[@knottywoodyarn9629]

Thanks so much!

[@irinialexandridi3522]

I would love to dye the wool I use for weaving. So your videos are godsend.

[@sararichardson3162]

Thank you so much for explaining everything! It’s exactly what I needed to know. Great video!

[@Darciphenix]

thank you, these videos are so helpful.

[@stoopsyo]

You explained the metric system well my dear.

[@SusanArnold-pc4wj]

Thank you

[@liddlemountain7245]

Thank you so much for this!

[@ispeaktheveritas]

this is SO helpful, thank you!!

[@lisamacaskill3589]

How long does the dye stock last once made up? Thanks

[@PrettyGirlsMakeFaces]

Thank you so much this was incredibly helpful 😊

[@ChasingSunRaee]

Thank you!!

[@RichFarago]

Thankyou for this series. This is excellent. Would this method work for wool balls and will the dye be permanent?

[@dipthepanda]

This video is very helpful. Although I think your math is off. If I take 100g dye powder and 100g water (since 1ml weighs 1g you could easily convert it) you would get 200g stock, consisting of 50% water and 50% dye. In chemistry you call that a 50% solution, not 100%. So, 100g of a 4% stock would mean 4g dye and 96g water. I admit that both ways wouldn’t make much of a difference, as long as you are consistent each time you mix.

[@mirandavikanderson6958]

You just confused me. 1g for 100 mls of water. Is easy to remember. For a 1 % dye salution but she hasnt talk about the weight of the goods yet. And if u wanted to dye a true black, your are going to need a 4 or 5 % solution needed or your just going to get gray. Because the wool is a whiteish of white color.

[@user-ui7wc9yw5j]

You're right. The percentage is how much of the acid dye is in the solution. A 1% solution is 1 gram of dye in 99 ml of water. 50 grams of dye and 50 ml of water is a 50% solution. A 100% solution is 100 grams of dye with no water.

[@fralou1]

I love your videos. Thank you. Please make more. There’s some colourways i would like to learn. I think it’s called decomposing fade set???

[@DanielWSonntag]

Wondering if I should check the skeins I dyed already... Soak in soap and water to see if the colors set. Now I don't know if I used enough acid...I used some vinegar, but now I'm not sure if it was enough to set the dye. 😩 Update: so I just checked the last skein I made which had some deep purple in it. No bleeding, just a slight hint of color in the water. I may just not have rinsed it thoroughly the first time. Whew. But good to know how critical the acid level is!

[@surmaibyshachi]

Hi, I want to paint on silk using these dyes. How much vinegar should I add to an 8% stock solution if I make 100ml of it by mixing 8 grams in 100 ml of water. Also should I use hot water to mix the dye or normal water will do? TIA

[@patogden856]

Hi, Pat here. Is there any way to remove acid dye from wool. I mistakenly mordanted my wool with aluminium sulphate before using the acid dye it is washing out big time and wondered if you have any tips to remove the lot. Appreciate any tips. Thanks

[@mirandavikanderson6958]

Safety first forsure

[@lukastemberger]

Great video! Is there a way to use acid dye to paint a wool jacket using a brush or a sponge or similar? I was thinking of trying it and then hear it up with a steamer to set it. Would that work?

[@lamoded7926]

thanks😭

[@derartuamindemsho7052]

What about strength of electrostatic force as PH decreasing

[@armellechaumont4155]

Thank you for your advises ! I am using Dharma acid dyes: I use to mix 1, 5 gr for 50cl for a 100gr skeins: is that wrong ??? Many thanks !!

[@FoodandFilament]

Is it necessary to make stock? Can I just use dry dye in a dye bath? Can you re-dye if you did not get the color saturation you intended?

[@pamyclark1263]

To get coverage for 1pound of yarn in a 1% solution, will the results be the same density if I use the correct weight of dye for one pound but have it swimming in 250 mls of water instead of 100 mls?

[@akjilane1137]

for 4% stock solutions, can I use 4gram dyes and 96ml water?

[@danielbikas3341]

No

[@melinapanagiotidou]

No. Use 4gr for 100ml water( 8 gr for 200ml water etc)

[@patriciabershak3821]

Yes, you sure can do it that way! Either way works, just choose the method you like and be consistent. I have a little page on my website, dyebook.com/tools/stock that uses the method you are asking about.

[@ginaparlange5439]

How do you dye a sweater ?

[@marcocastagnetti7086]

Hi there, (great video) I would just like to ask one question, I plan to dye 3 wool jumpers that are all the same also in colour (ercu) that weighs 900g each the deepest colours jet black, brown, olive by stove method the pots by jacquard are 1/2 ounce by amazon UK how much do I need per jumper. Best wishes Marco.

[@katt7938]

Marco Castagnetti I didn’t see her reply ,how did you get on

[@saraphinacrochets2781]

How do you weigh out your grams?

[@knottywoodyarn9629]

I use a digital kitchen scale that has grams.

[@lauriebieda4498]

Would it really have not been simpler to just say,1cup of water add 1tsp. Of dye,good god

[@sarahlou5777]

Clearly not as she said they all weigh different 😂🙈

[@DanielWSonntag]

Now I'm finally dyeing yarn! Shelburnefallsyarn

[@Sunnydazeknits]

Where do I find the % of dye stock solution needed? It is not in the information on the container. Where did you find this information? Thank you!

[@hitzchicky]

If you go to the website of the manufacturer, they'll spell out the % they used for the color swatches. For example, for Dharma Trading Co, if you scroll down the page of the acid dyes, it'll tell you the % they used.

[@mungunanu1264]

Cool video, i have a wool workshop in Harbin, China, we also dye our wool by hand, after watching your video i calculated a % and i now know my solution's %, when i first started dyeing didn't really went through all this and just started making test runs and got the result that i liked and sticked to it, hope you make more videos in the future, if you wanna check us out please visit, @mungunanumungunanu, this is our facebook page, thank you for making the video and good luck

[@knottywoodyarn9629]

I will absolutely check you out! Thank you for the encouragement and I so glad it was helpful. Cheers!

[@ameliemarez2206]

I would like your help. I just emailed you.

[@docteurshepherd]

Literally the first thing I did was open them up and look without a mask.. oops..

[@florab14]

I'm sorry but the math is completely off

[@devynchae223]

florajanurik THANKYOU! I was hoping to find useful videos but when you can’t do the math you shouldn’t teach it! This could be dangerous if someone uses other chemicals and thinks this is how percentages work...

[@teruchuu]

I think the math is correct - it's just ratios. This kind of math is very similar to baker's math used for baking bread. All the ingredients in a given recipe are weighed relative to the amount of flour, which is always equal to 100%. if you're making a 500 gram loaf of bread, 500 grams is the total weight of flour; the amount of water added to make the dough is expressed as a percentage relative to this weight of flour. A 50% hydration loaf would mean you'd need 50% of 500 grams, which equals 250 grams of water. This is the type of math used here, which is simpler and expressed differently than solution chemistry. In short, the amount of dye powder is expressed as a percentage of the total amount of water used to make the solution. This is why 1 gram of powder equals 1% for a solution containing 100 grams of water. 1/100 = 1%. If you want the final solution to be 200 grams, you would need 2 grams of powder.

[@sewobsessedmama8851]

You made it make sense thanks a bunch!
