Give me your painting ideas for my sweatshirt

Hello everyone! Long time no read, right??

Today's post I'm asking all of my readers for advice.... I bought this really comfy extra large purple pullover sweatshirt at the thrift store today, and it has no design on it. The sweatshirt looks a bit like this, minus the V stitching.

I was thinking of perhaps doing a little painting on the front, some design that could be cute. If I can get a bunch of awesome ideas from my readers, maybe I'll find the perfect idea to decorate my new sweater.

Let me know in the comments what you think would be cute. In case you're all wondering, I love cats and rainbows. :)

I look forward to hearing from you!
