As I was putting these pieces together, something occurred to me.
but I could TOTALLY do this with fabric!
I know it's silly I never thought of it, but I was sort of entrenched in my thinking - "This particular method is for paper only!"
But there's no reason I couldn't use the same method for cloth - maybe just add some stitched in invisible thread in the corners and centre bottom and top to account for the extra weight.
See you on Friday with the finished pieces!
