I mentioned last week in this post that I had trouble getting the paper backing of the Wonder Under fusible web (<-affiliate link) to peel off the fabric. It was super frustrating as I followed the directions exactly as explained on the instruction sheet that came with the fusible web.
I had more than a few appliqué pieces (big and small) that looked like this:
Last summer when I made my travel laundry bags, I used Thermoweb Heat’n Bond Ultra Hold Iron-On Adhesive-17″X36” (<affiliate link) to fuse the letters in place and I had no trouble at all getting the paper backing to release.
After a quick internet search, I discovered that this is a common complaint when using Wonder Under fusible web.
Thankfully, there is a trick to getting that paper backing to peel off.
First, trace your design on the smooth side of the Wonder Under and iron it onto the wrong side of your fabric.
I had to increase the amount of time I left the iron on the fabric. In fact, I found that it worked best when I doubled the recommended time. You may want to experiment using scraps to find out the amount of time that works best with your fabric and your iron.
Make sure to allow the appliqué piece to cool completely.
Next, cut out your design along the traced lines.
With a sharp pin, score the paper backing in the center of your design.
Starting in the center, peel the backing off.
Next place the appliqué piece in the position you want it, with the fusible side down and the right side of the fabric facing up, iron in place.
If you look closely you can see that after ironing the star in place on the ornament, there were still a couple of points that hadn’t fused properly, so I had to iron it again.
I bought a meter of the Wonder Under as it came so highly recommended, but once I’ve used up what I’ve got, I’ll be switching back to using Thermoweb Heat’n Bond Ultra Hold Iron-On Adhesive (<affiliate link)-17″X36″
for any future appliqué projects.

December 20, 2020 10:32 pmThanks for this information. It helped me get Wonder Under off my applique and ready for fusing. I have used Wonder Under for several years . . . in the last 1 – 2 years, it has been much more difficult to remove the paper backing. I don’t think I am doing anything different. Now that I have only a little left, I think I will use it up and then change to another product.

May 31, 2020 8:28 amI want to repair a large weakened part of my favourite sheets. This is on the bottom sheet. I would rather not fuse another piece of fabric to it. Is there a way to use wonder under or another product on its own.

Wonder Under is designed to fuse together two pieces of fabric, so it wouldn’t work for what you’re wanting to do. If you fused it to your sheet, there would still be the paper backing on it. The only thing that I can think of that might work, is if you fuse some light weight interfacing to that weakened area by fusing it to the side of the sheet that faces the mattress.
I can’t say for sure how long a repair like that might last though as I’ve never done it.
