Zero. I mostly gather supplies that I have been wanting to bust out. I try to work from those limited supplies. For me, cutting a card base takes far less time than rifling through all my junk to find inspiration. Though, full disclosure, I have plenty of half sheets floating around in the back of my scrap box and will pull from there first until I run out, which would be wonderful!
Last year my plan was to use up some odd sized envelopes, which I did. This year I am going to try to use up a lot of odds-n-ends. I am going to try to use up some of those embellishments that I bought to make quick cards that have been languishing in my stash.
I believe in butter.
