not sure if all this info belongs in the FROG section, But its the best I can do. I wanted to mention that I found trimming the fabric with a hot knife to be worth every penny. Not to mention it makes a very satisfying sound when cutting. The cutter used in the videos are the german manufactured hot knife that runs $200 plus! I found this one from Carolina knife Co. for $99 Bucks (plus $20 shipping)! hot_cut_knife It appears to be of good quality and sturdy. it doesn't have the led light to illuminate your work, but I didn't think it really needed one.
