Knits are infamous for rolling edges. Generally I handle them my serging the edges before prewashing and serging the garment as soon as the knit- fabric is cut. But thereI’ve acquired a new knit that rolls as fast as it is cut. This is a problem. It’s not that easy to unroll and serge. I find that I’m changing the size of my finished garment i.e. I’m sewing the garment significantly smaller than cut. Should I add more ease to compensate? How do I know how much to add? Is this something I have to make a test for each garment? See how I can really obsess?
I decided instead to try out a few solutions to the rolling edge. I purchased Terial Magic
I purchased mine from Amazon but I’ve seen it in several places. It came with a spray, so I tried spraying. Oy vey!
Look at the selvage on the left of that pic above. It took 8 different spaying plus ironing without steam and it is still not flat. Next, I poured TM into a small bowl, painted and ege and allowed to dry over night:
TM is a winner!!!! Needs only a light press without steam. Heck I think I could skip the pressing.
Another recommended product is Blue Glue
I’m told it must be the blue, washable, school glue so that’s what I bought for the first trial. I squirted it along the cut edge
Admittedly this may be a user error, but I couldn’t get an even application with out the help of a small spatula
Once again dried over night
I hang things that-need-to-dry-a-while over the shower curtain in the guest bath.
Don’t have a good photo to show you, but the glued edge curls as it dries. I gave it a shot of steam and pressed lightly to unroll the edge. I did have one place that was tightly curled and would not unfurl. Made me glad I started by cutting project size pieces 2-inches larger than the expected finished project piece. I can just place my pattern above the edge far enough to exclude the furled edge.
Both products performed. TM was better at producing a flat edge . Blue Glue has some additional attributes. It’s a lot less expensive — by far. Easily available and also functions as a washable resist. Yes, use it as a resist which will wash away and be gone. I’ll use the TM as long as I have it. Not sure I would buy a second bottle because, I’m cheap.
