Nylon shirts
 

I have a bunch of my grandson's soccer shirts that are mostly nylon material, is there any way to stabilize them so I can make a t shirt quilt. I have made him 2 others but shirts were mostly cotton. I am at a loss Thank you

I would get some light weight fusible interfacing actually, I'd get a small amount of a woven, non- woven & a knit. Cut one of the arms out and do a test to see if the shirt will take the heat needed to fuse.
If that doesn't work, you can try cutting a muslin square the same size as the shirt square, hand baste (like hand basting a quilt sandwich), then treat the 2 fabric pieces as one.

I haven't used it, but for this project I would try out Terial Magic. You would cut the shirts first, then dip the flat fabric in Terial and allow to dry before ironing (I think). It is supposed to stiffen fabric to a cardboard feel but washes out completely later. I think it is used for fashioning fabric flowers (not washed, of course!) and other types of projects. I'm thinking it would work better for nylon shirts than an iron-on interfacing, simply because nylon often cannot take enough heat for a fusible to work. Anyway, I'd get a bottle and try it out. Here's a link to it on Amazon:

I have used fusi-knit for my grandsons' hockey jersey quilts. The jerseys are made of polyester and/or nylon and worked well. I do quilt around the logos and numbers.

Well that's interesting. One of my custom brides. I tried to cancel it and now can't get the quilt to load��
