If you're kntting the stitches across the row together with the corresponding st of the cast on, you'll create a roll or hem
. I agree that that's what this sounds like. It may come several rows into the lace pattern and sometime there's a yo, k2tog row at the halfway point between the two knit together rows. When you make the fold this yo, k2tog row forms a picot edging on the gloves. If this instruction shows up later in the pattern, it may create a tuck in the gloves. You may have a better picture
of the gloves than this (last pattern). See what the edging looks like. If it's not ribbing, it may well be a folded hem.
