I am ready to sell off all my supplies and reclaim my studio as a spare room. Zero time to work, coupled with a lack of desire when 'making for money', turns my studio into just another junk room. I do wish I could turn my art into a 2D item to print onto things, but alas my crafts do not translate well to tee shirts and coffee mugs.
If you can find joy in doing art that others want, then why not!? You can still throw in a few experimental bits for your own enjoyment as well! Stick to the bread and butter, but maybe some of the little sides of jam will catch on as well ;)
