Hi everyone

I know how to(have done) dup st on stockinette stitch (for designs, initials,etc) but is there a way to do a dup st on garter? I have a garter border going on a baby blanket, (5sts) just realized that I have a couple of rws of a boo-boos (bumps are on the WS)

so I thought maybe I could "cover up"the "boo-boo" with a little design or maybe baby initials

any thoughts...Thank you Cheley
