This is what I gave as teacher gifts this year and a thank you to the leaders in our Sunday School class. I got the idea from here, but tweaked it just a little.
She has a thorough tutorial and its easy to follow, but here are my (minor) modifications.
*I had a really hard time getting some of the labels off, so decided to leave the front one on. (Keep in mind, I did about 20 of these, and was too lazy busy to be goo-gone-ing (technical term) that many. The back label came off just fine, so I made the back the front.
*I did not spray prime these, instead bought spray paint suitable for plastic. It said no priming needed and I was all about skipping that step.
*Since you could still kind of see the label in back (even after 3 coats of paint) I opted to punch a scallop circle out of scrapbook paper and modge podge it on to cover the label. Worked out just fine and had an added touch of color.
I have a handful left over, so will be finishing them in various ways, just like the original. I'll do one in black with a "G" for our kitchen sink. I might do them for Valentines day with a big white heart? I already have the red paint!
