When you want to buy something and it is not necessary think about where your stash is going when you die. Likely no one in the family will want it and either the trash or a cheap garage sale will catch it. So use up your stash to keep it out of the landfill or being sold for nothing. Best way I can think of not to buy anything else. I, too, wanted something I saw when I saw it whether I had a project for it or not, but now have so much 'stash' I will never use it all in three lifetimes, so have to use as much of it as I can. You can get really creative with what you have.
My 2 cents for the day.
