Sewing Zippers 104 - Zipper Plaques for Cushions

Sewing Zipper 104 demonstrates two different techniques for sewing a zipper plaque on a boxed cushion. A zipper plaque is basically a zipper sewn on the box seamed edge of a cushion used to insert or remove the cushion foam. The first zipper plaque technique demonstrated is a standard zipper plaque installation while the second is a hemmed zipper plaque technique with a hem that covers the entire zipper. Visit www.sailrite.com for more zipper installation videos and all your cushion supplies.

Excellent video! I've sewn clothing professionally for decades, but I find I'm always looking up videos for home dec projects. Learning never stops, you know? You've done a great job with this. Thank you!

I have made tons of cushions watching your videos over the years, but came back to reintroduce the perfection knowledge as I am going to sew covers for our 2.0 hot tub cover that we have designed. it will be closed cell foam that will be covered entirely in fiberglass and covered with your new line of Sattler® Marine Grade fabric and waterproof zipper. wish me luck!!

Your wonderful videos are what convinced me to spend $1800 for a Sailrite Fabricator, and hundreds of dollars worth of thread, feet, basking tape, and lift-the-dot snap supplies.

Thank you for the zipper tutorial ! Especially , the flap covered zipper.

These are some of the best informative videos i have seen. No shitty music, just very well explained ways to do the jobs on all of the videos. great stuff!!!!!

Thanks!!!

Great video and instructions. Thanks team Sailrite. Got my basting tape from you, sent to New Zealand, Thankyou so much. Super happy.

[@cookingsavvy7407]

This was EXACTLY what I was needing to sew today! Thank you so much!!!

[@MileyonDisney]

I just saw this technique used to insert a zipper in a dress for the first time yesterday. Great way to add a zipper!

[@SailriteDIY]

Yes, it is one of the many ways to install zippers.

Thanks, very helpful videos, just embarking on two bench cushions!

Thank you for de-mystifying the zipper! Nice group of videos!

You are welcome!!!

My brother is an upholsterer and my father before him. They both would use the second variant for boat cushions, patio furniture, and hot tub covers.

Great description on how the make the plaque. How to install it? How much to leave on the ends to attach to the sides?

[@khanlin132]

Should the size of the side of a box cushion be the exact same size as the foam when finished? I mean I know you need to add the seam allowances but other than that should the finished side of the cover be 3" if the foam is 3"? Or should the cover be smaller so it ends up stuffed very tight? Thank you for the cushion zipper video. It was very clear and this is the first time I am using a continuous zipper so thank you for explaining that also.

Hi Karen, Below you will find the instructions on how we determine our boxing width. Determine boxing width by measuring foam thickness (include batting, if any, under slight compression during measuring). To this measurement add between ¼” and ¾“, I usually just add 1/2". Keep in mind that thinner cushions look best with more allowance added and thicker cushions look best with less. Basically adding less of an allowance will allow the seams to roll into the edging of the cushion. Seamed Boxing - Boxing length should be the exact length of each plate edge, if sewing a separate piece of boxing to each edge of the cushion.

@@SailriteDIY Thank you that helps. Sorry, one more question...Does the Sailrite calculator help to determine how much material is needed to create bias piping with 1/4" cotton cording, 1/2" seam allowance so total 1 1/2" wide. I need to sew 4 seat cushions with piping top and bottom edge and 4 back cushions with a rounded top also with piping on front and back edges. I have estimated with a little extra that I need a total of 36 yards of 1 1/2" material on the bias. How do I figure out how much 54" wide material I will need for all of that cording? Thank you for your help. These will be outdoor on a porch so I will also be needing the Silkfilm calculations.

[@sherryfradley8077]

You state to use the width of the foam plus the width of the zipper tape. What about a seam allowance for attaching to the top and bottom cushion pieces?

[@SailriteDIY]

Typically for a cushion's boxing and zipper plaque we will cut the boxing to the thickness of the foam and then add 1/4" to a 1/2" (so a 4" thick foam would have a boxing that may be cut to 4 1/2"). When the boxing is sewn to the plates (using 3/8" seam allowance on both sides it will be slightly smaller than 4" in thickness making a nice tight fit. A zipper plaque is done the same way except that the width of the zipper is added to the boxing width. See videos on cushions for detailed instructions: www.sailrite.com/easearch#!&ea_q=cushion%20videos

I believe it's 'placket' not 'plaque' A zipper jig makes this much easier, even if it's just a bent fork. Putting the pull on is tricky without it. Clover Wonder clips are very helpful too.

[@SailriteDIY]

Thanks for sharing your tips and advice! You are correct about the placket, but we (Sailrite) intentionally coined the term "zipper plaque" instead and wanted to see if it would catch on over the years, and it has. Believe it or not Sailrite also came up with the description "Asymmetrical Spinnaker" in the 70's and it became the standard name for that type of sail. Fun tips!!!

[@jos9569]

@@SailriteDIY I find your videos REALLY helpful, even if they're just a review of something I've already done. I've sewn RV mattress covers, wedding gowns, and much more. Next project is a marine vinyl cover for a daybed for the trailer. I'll be cutting down a Tempur Pedic mattress to make the back and arm cushions.

[@mariamidura3089]

Would this work on regular outdoor fabric?

[@francklardellier6777]

What kind of needle you use for this plastic zipper .mine brokes every time

[@SailriteDIY]

We were using a #20 needle with V-92 Polyester thread and this is the zipper we used: www.sailrite.com/YKK-Continuous-Vislon-Zipper-Chain-White-5

Don't you need to put a zipper stop on this zipper?

[@debbiehoffman5759]

When you’re measuring the width of the fabric, don’t you have to add some for seam allowance??

[@SailriteDIY]

The boxing should be about ½” thicker than the foam. An example is a foam that is 4” should have a boxing strip cut to 4 ½”, in my opinion. This will result is a nice and tight fabric cover over the foam and thus the stretchy fabric should fit very well. Seam allowance for that should be ½”. That means you top plate will be almost 1” less in both dimensions (a ½” all the way around) after sewing it to the boxing. The boxing will result in a 3 ½” finished width after sewing. This should make the cover nice and tight.

[@debbiehoffman5759]

@@SailriteDIY Thank you for responding, I wasn’t expecting that☺️. So, I’m making a bench cushion, the cushion itself is 3” high, are you saying instead of allowing for a 1/2 seam allowance, that I should cut the plates to the exact size of the cushion and sew it together with a 1/2 seam allowance? Or cut it the total length and width plus 1/2 inch? Thank you for your help, I’m a beginner, so still learning.
