Gonna be starting in the next few days and i am going to be using WoF's templates (Thanks Wizard!!) to cut the more simple pieces. Chest, abs, shoulders. I am going to be using Sintra since I have used it before and feel comfortable with it. Plus an 8 ft sheet is $20 and i can pick it up locally! Just wanted to know if you guys think 3mm will be thick enough. 6mm as I have seen in some other threads, seems way to thick to me and the gauges go from 3 to 6mm. There is no 4 or 5. I'd appreciate feedback on this.
