This is a pretty easy and cheap gift to make or use for yourself. I can't find the blog I originally got this idea from, so if you see this (which I dought they will!) I'm sorry I couldn't link your site! All you need is a $2 tile from home depot (not sure of the price anywhere else, that's where I got this one!) it's the larger tile that is bigger than your hand. You can either get the rub on transfers for this or if you have an electronic cutter (I have a cricut) you can use some vinyl, which in this case is what i used.
Then I bought a bag of wooden knobs at hobby lobby - they need to be flat on the bottom. I believe I got 12 knobs for $2.99. Paint (you know I busted out my spray paint) these to match or if you want you can leave them "naked"
