My $99 singer handled the fabric great. I have a walking foot, which helped as well. If you don't have one, I would suggest looking into getting one.
I think it looks great! It's a relief to hear that the neoprene wasn't too bad to sew; I'm worried it's going to fry the motor of my little ol' Kenmore sewing machine! (I'm still procrastinating on mine... you aren't alone, MaulMaus. ;)). Where did you get your neoprene, BTW? I ordered mine from StretchHouse, and was wondering if it's the same thickness. I'm working on ANH Leia Senatorial Gown (I know... TURNCOAT! :) Honestly, just a LOT easier to get done for Halloween!) and Ep III Obi Wan for hubby (DOUBLE TURNCOAT!) now, so after they are done, maybe??? Frankly, I think I'm just too scared of it to start. :o
