Extra stitches than the pattern calls for
I started knitting a baby hat that says to cast-on 72 stitches. I did that and continued with the pattern for a few rows before checking my stitches again. Now I'm counting ~78 stitches. What do I do? I'm thinking I can k2tog a few stitches near the stitch marker. I have a heart pattern coming up in about 15 rows, so should I wait until just before I get to about the 14th, or just do something now?
