It is always a struggle to come up with a unique card for Valentines. I don't silk screen anymore, so I have to figure out something innovative with fabric. I don't fuse either.
I love denim and collect old jeans to make quilts. I thought of using the seams that don't normally get used in the quilts and I have loads of funky yarn when I made funky scarves. I still make some occasionally, but still have great yarn. I cut the denim and heavyweight interfacing the same size and sewed on a whole handful of yarns with a stepped zig zag on the trusty Singer 401. Never made even a cough or sputter, went through like butter. I did use a jeans needle. Then I used a blindstitch on the edges to hold the denim and interfacing together, no glue. I did use double stick tape on the cardstock. I wish I could have made more, but after 30, I wore out. All are given away, so all I have left is the photo. Super fun.
