i made my bag on a regular cheapo sewing machine. It's not really the power or the strength that's the problem, it's just the fact that it won't feed the fabric by itself thus making knots, you have to "help" the fabric go through. also, do everything on the outside BEFORE you make it into a 3D shape. The hardest part was the "bunching" of the material since the sewing machine was also very "dinky".
