From Pattern Notes:

The pattern assumes you use Sugar n Cream or Peaches n Cream or Lion Cotton, as they will knit to this gauge. With Sugar Babies yarn, I used size 8 needles, cast on 27 sts instead of 25, knit until square, bound off so that 5 sts were left and otherwise followed the pattern. For Aunt Lydia’s Denim yarn, I used size 7 needles, cast on 30 sts, knit until square, bound off so that 5 sts were left, etc. You may also have to alter your button size if you use thinner yarn.

Suggested Variations: It seems to me that the basic pattern could easily be altered. I have considered making these in a seed stitch, moss stitch, or you could use a non curling border stitch pattern and make the center in stockinette. It would be possible to incorporate a stripe pattern with the garter stitch as well. I designed this when we couldn’t find an easy production/quick knit baby bib pattern for Stitching Smiles, a group in Nebraska that knits/crochets items for charity.
