I have made 2 chenille blankets (small), and used extra sharp small bladed scissors that were supposed to be good for this the first time -- NEVER AGAIN!! The second time I used my electric scissors (mine are Black and Decker, and pretty heavy duty). This time it was A BREEZE!!
Just thought I'd mention this for those of you who already have electric scissors (they were pretty popular in the "old days", well, 'medium old days' anyway!!!
Andrea has a lot more experience, so she may have some insight on this.
