Over the years, I have discovered, though, that some things are what I deem "splurge-worthy." These are items that are of such high quality and usefulness that I go to them over and over. This makes the per use cost minimal even if I spent more at the outset.
I am less picky about stamps - rubber, foam or acrylic - and have been known to buy every brand imaginable if I liked the design. I find that they give a unique feel and texture I can work with even when they are cheap.
What's "splurge-worthy" for you?
