I trace the furthest back piece on a square of the fabric, then needleturn the other parts, then cut out the piece to attach. So try this instead of the pellon.
I have all the flowers ready but when I tried to sew them by hand, the glue made it too tough to sew thru. I am now using my zig-zag (very tiny with matching thread) sewing the flowers together. I think they are working out well.
Thanks for the suggestion. I will try it with the next blocks.
