Years ago I use to use Krylon spray, but it was such a pain and messy and felt ugly when I touched the labels. I did the tape over them, I also used onlinelabels.com. I finally ended up biting the bullet and paying to get my labels done. I had them professionally designed and printed. It was expensive in the beginning, but with time they paid off. My sales went up and I got lots of compliments on the labels alone. I hope you end up finding some sort of a solution, I know what a pain it can be.
