I do a lot of embroidery and love it! I put a thin white flannel on the back and embroider thru both layers. It gives it a a nice feel and also hides all those ends and carryover threads. I usually use two strains of floss because when I put so much work into my piece, I want to be sure that it can be seen from a distance. If I am working on a very small piece (or small area), I sometimes vary the threads, one in small areas and two for the most part. Have fun and enjoy!
