Start simple. Box cutter, rulers,(cork backed if possible) punches from Harbor Freight. You can get a lot of tolls cheaper if there are not labeled leather working. Make key fobs, braclets, minimalist wallets. They are small prices of leather that you can practice the fundamentals over and over. And you then have some small x mas gifts for friends and family. Jlsleather a member here has some free patterns on his website and also he sells small pieces of project leather on his Etsy site. All his leather is Hermann Oak or Wickett and Craig. Good stuff. Good luck have fun and say good bye to your retirement fund. Lol
