Her question was: What is the best die cutting machine to cut fabric?
She probably does not know about the Accuquilt or Sizzix cutting systems, only knows about the ones that uses software.
I free hand cut the fabric to fit the die but I buy precuts to fit as much as possible. For scrap pieces I cover whatever shapes on the die that fit. Doesn't have to be all the same fabric. I cut all the blocks for a large Drunkard Path quilt in 20 min this morning. I used left over layer cake squares I had from other projects. The scrap fabric I have left from cutting is rarely big enough to get a hexie out of.
