Stained Glass work and Specialist wooden projects.
My shop offers a number of publications and tools related to Stained Glass Work.
The basic text that I would most recommend is the 'The Complete Stained Glass Course' by Lynette Wrigley and Marc Gerstein. Amazon usually have used copies for sale so you don't need to break the bank.
Let me know if there are other items that you'd like me to include here.
