Welcome to the maddnes and IAP, Great to have you!!
I agree with all the responses above. I took my wife and we took the pen class together, way back, Then bought "her" turning tools after purchasing the lathe. She kids me about this now since she doesn't come into the shop much. But, showing her that money can be made and Christmas gifts are covered allows her to over look some of the expenditures. But, I agree with some others. Buy stuff, use it, and ask for forgiveness when she happens into the shop or show her what you have made and then she is sure to ask how you did it and then drop it on her you HAD to have yada yada to do it. This helps alot. GOOD LUCK
and again welcome, looking forward to seeing your work!!
