We're not using bibs yet, but before the little tike arrived, I whipped some out real quick. No, seriously. They each took about 20 minutes, and that's including ironing.
I pulled some scraps and leftover fabric and mixed and matched to my heart's content. I used this tutorial from Chickpea Sewing Studio - it was so simple! Now we've got a little stack of cute, fun bibs! :)
