Shirley over at Stitcherydo recently had a post where she used up and used up and used up all her fabric pieces until she was left with the tiny unusable bits. I perhaps don't go quite as small as she was left with but I certainly use quite small pieces for my Aquariums.
Especially if they are a little glitzy!
These two are about A4 size each and only have 'L's or masking tape around them at the moment so I can see where to hand stitch and bead too before trimming. Cutting through hand stitches = mess and loss of beads.
I'm off to add some more before trimming and framing.
