3 Ways to Make 1/2 Square Triangles

[@sherylhelt468]

I used the formulas at the end of the video at 10:40 (9" square to get 8 4.5" squares to have 4" finished squares), but after I cut them apart, they were 4" and not 4.5". I read in the comments (after I did this) that they starting square should be 9.75", not 9". I had to redo mine, but adding the .75 did yield the 4.5" squares I needed.

[@geraldludwig9402]

She didn't mention how big of square to start with when doing the 8 at a time...

[@stevansilva9821]

I just counted the squares on her mat that the square was lined up on and saw it was 9”.

[@paulinelarson465]

To make different sizes, - decide on finished size of half square triangles needed. Then add 1/2 inch to that measurement to cut the two squares to make two half squares triangles. Two 4- 1/2 in. squares make two 4 in. half square triangle squares. To make 8 pieces at once, think of a four patch of squares, each set of squares making two half square triangles. If you make each patch set 1/2 in. larger to get the two half square triangles, then imagine putting four of THOSE square sets together - in a square. You have added 1 in. to get the size of the squares needed to make 8. Two 9 in. squares will make 8 - 4 in finished pieces. Two 7 in. squares will make 8 - 3 in. finished half square triangle pieces. Two 11 in. squares make 8 - 5in. finished half square triangles.

What size fabric square do I start with to make the eight at a time HSTs?

[@terisparkman9814]

I like to use the Clearly Perfect Slotted Trimmer to square up my half square triangles prior to ironing them open. It’s so quick & easy.

[@belindagatty581]

Very helpful for my next project which is half square triangles so I can practice to make my ultimate project, tree of life,any suggestions. I enjoy your teaching

[@melissagarcia4484]

What is the name of the small thin ruler that has quarter inch on both sides and a center I really liked your demo thank you

[@RileyBlakeDesigns]

Hi Melissa, it is an Omnigrid Quarter Inch Seam Marker

[@m0ther0ne]

Thank you, I always wondered what the math was. You made is so logical I can now do the math for larger HST. The other method of sewing all around the edges, is the maths the same?

[@cathycomfort1800]

Thanks for this easy and accurate formula! I will use it constantly in my quilting.

[@barbaramarshall5271]

Thank you that wwas awesome, I love it when I get a really clear explanation for the how's and why's. Have a great day Blake😊

[@juliecaywood8083]

Thank you this was great! I am "self- taught " and this has been so clear and concise.

[@lindahall2197]

So I'm not getting what I'm doing wrong have 1 /78 inch square so I get a 1 1/2 square and it's not right with other pieces. Help

[@janmorrison7924]

Educational I didn’t know how to determine size of squares to determine size I needed. Thanks

[@leontina59]

Thank you!!!! I have just started to learn quilting and have been so frustrated trying to find someone to explain the best way to mark/ cut HST/QST, after watching your tutorial i am no longer frustrated, you are amazing!! Thank you again! :).

[@daniellebrewer8105]

What is the name of the quilt pattern behind her? I went to the tensisters website but can not find it.

[@debstumvoll855]

Thank you for the clear demonstration 😊

[@almaherrera1830]

Can you share the pattern of the quilt behind you ?

[@carmengeddes5153]

Hi Alma, the pattern will be available soon on tensisters.com as a FREE download! Also, the class will be here on Riley Blake KZbin channel-- FREE!

[@RileyBlakeDesigns]

The quilt will be available soon on Carmen's website: www.tensisters.com/

[@lisabrabham7137]

Good idea to mark the sew line! Thanks.

[@sheilacripps9340]

Thank you Carmen! I finally made my first ‘perfect’ HST!! Please forgive me, I used some of your tips and one other persons tips. Yesterday, I tried to sew one and I was dismayed!! Until I get really good at judging that 1/4 inch on either side of the center, I’ll be drawing my lines!! Again, thank you!!! :)

[@rachelwest337]

Where can I get that 1/4 ruler

[@iamtvblake]

What SIZE is the big triangle? Did I miss it?

[@Lexi-mw7ul]

9 inches!

[@ninacrump8864]

Thank you! 🥰

[@camagnuson6108]

This is an excellent demonstration. Thanks. Do you happen to have that last chart showing all 3 methods in a form that could be downloaded? A PDF of that would be great! Thanks.

[@cynthiafed]

At the 10min 40 sec mark of the video a picture graph of each is shown...long enough to snap a screen shot picture to the download. Hope this helps! 🤗

[@carmengeddes5153]

Thanks for watching Cheryl!

[@twinstar9]

@@cynthiafed long enough? Haha all you have to do is pause the video.

[@twinstar9]

You didn't go to "either side" of the first half square triangle. You made only one cut and you didn't say which side to cut on and why.

[@princessagatha9991]

Because she only needed one square the 1/4” seam allowance is on the half side that she didn’t need. Doesn’t matter which side you pick to cut it on, it’s symmetrical until you cut it. If you need two you have to add in seam allowance because it can’t come out of the side you’re cutting. If that isn’t clear, just follow the instructions and see for yourself. Sometimes verbal explanations don’t make sense to me (particularly in knitting patterns for example). If the directions are clear I just follow it to a tee and usually the logic becomes clear.

[@twinstar9]

@@princessagatha9991 Yet another barely literate person who knows zilch about grammer. Are periods and capitals anathema to you?

[@princessagatha9991]

Aren’t you a treat.

[@cfleyfel855]

Isn't the formula for 8 HST finished size of 4" like this: 2 x 4" + 1.75" = 9.75 " ?

[@livinthedream4479]

She did not tell what the measurements should be. Not sure where you got the 1.75 inches

[@livinthedream4479]

I feel like it should be more like .75 in extra

[@cfleyfel855]

That's how I always calculate it and I even round it up .Better too much that not enough .

[@TayaSews]

Yes. Multiply the finished size of your HST by 2, then add 1 3/4 inches. Cut two squares to this measurement.

[@traceybartlam5940]

Great explanation, thank you

[@susieq627]

That was so great thank you. I need to buy the big rulers you have there. What are they called?

[@susieq627]

@marlene riggs thanks. Your the greatest.

[@susieq627]

@marlene riggs they are actually called acrylic rulers which someone new to sewing would NOT know. So next time u get up at the ass crack of dawn to troll and fight with strangers..at least sound right

[@katiegrace6968]

This is awesome!! Love the method for 8 hst

[@twinstar9]

"The inside of the half square triangle." Huh?

[@twinstar9]

She didn't set the seam. She didn't cut straight.

[@aishterubaka]

This is painful! Speak properly and be clear with your directions. If you knew how to do it properly without stuttering this would be a good tutorial!

[@princessagatha9991]

I found her to be very clear. I’m not sure why you’re being rude. If this isn’t the tutorial that works for you, then find a different one.

[@aishterubaka]

@@princessagatha9991 you and I have different standards. You must be deaf

[@melanieflaye4914]

Rude!
