I saw this pin on Pinterest and thought I could muddle through this one pretty well. I didn't really have step by step directions and it was fairly easy just to wing it. My "cactus" doesn't have any cool 3D shadowing effects or anything but I think it works! Maybe?
Here is the original pin:
And here is my finished product!
If you're looking for an easy DIY pin then this one is a good one to do. You really can't mess up. And if you do, just paint over it and start again. It's what I did!
