At least you are sticking to fabrics....over the years I have invested in several different things thinking I would do it forever...stain glass, painting, tole painting now quilting...each of those required a financial investment of varying degrees...and when it was over I kept them for years...I still have paints, but no interest! I finally sold the stain glass equipment after about 20 years...just in case I wanted to do it again.
Enjoy what you are doing...it's you!
