I'm (new to applique) working on a raw edge applique small landscape piece with flowers in the foreground. I have fused the landscape elements in the background to the background fabric. Now, should I sew down those pieces before fusing the foreground flowers and foliage? Or should I wait until I have all pieces on the background fabric? Some of the foreground will cover over some the background landscape. But waiting until I add the foreground pieces will make sewing the background just a bit harder (instead of sewing one line, I'll be stopping to 'jump' over stems, leaves, etc.).
Also, do you sew in any details you want to do in thread (like defining petal creases, etc.) before you put the applique, batting and backing together?
One more question: can I use polyester thread for defining details (no embroidery machine) or will it just pull out of the piece, as one salesperson told me.
Thanks for any help.
