I've been doing stained glass,sandblast etching and Kilnwork for 30 years as a hobbyist.Last month I began an apprenticeship re-leading & repairing 115 year old church windows with a gentleman that has built & repaired Church windows for 50 years. This is a 9 months to one year project. I feel honored to be allowed to do this.
