Thanks, I signed up for a class while at the thread store so hopefully that will help as well, "Leatherworker" I actually have a manual and have done an extensive search on the internet and couldn't find the answer maybe because they don't publish it or I don't know enough about what I am reading. For now I am going with Tex 90 and a 140 needle. Once I have gained some more knowledge about tensioning etc. I may go bigger on the top. Wallet guts and Biker Chaps / Vests are the heaviest it will see anyways.................Thanks for the help
