I have a Brother, Project Runway from a dealer, not the WalMart version. It sews through 12 layers of folded in half denim. I never have a problem with Prarie points or anything else. My Singer Featherweight us also good but the new Singers arent that good. Bernina, BabyLock, and Janome are all good and some of the dealers sell rebuilt machines that are very good.
