I hate waste. I hate using throwaway containers. So these plastic portable coffee cups seemed like a fine idea. But they get hot. So I need a paper insulator. Which gets (yep) thrown away. DH is the worst offender (he drinks the most coffee). So I made him one he could reuse.
I left a quarter inch around the edges for shrinkage from quilting. Fabric was right side out and Insul-Brite in the middle. Just enough quilting to hold it together. Then I trimmed off the excess.
Binding was two and a quarter inches folded in half, stitched around the edge and turned, then hand stitched down. Although I suppose it could all be done by machine.
I used iron-on velcro strips. But I don't trust their glue, so I stitched around them with my machine.
And the finished project. And, yes, I did throw away the paper one I used as a guide. *sigh*
