My husband is like yours. Completely supportive, even bought a serger for me on Craigslist and if he sees anything regarding fabric or sewing machines will email it to me (he loves Craigslist!) But he knows that I am frugal and most likely will pass up all these temptations, LOL.
He even suggested that I use the master bedroom for my sewing 'studio' and we use smaller, cozy retreat off to the side for our bedroom. so yes, that is my sewing room!
Congrats on your 40th Anniversary. We had our 39th this past March. Great marriages do last!
