When At First You Don't Succeed...
....shamefully refuse everyone's good advice to rip it out and instead just start all over again, but in a different shade of pink.
Pattern: The February Baby Sweater, by EZ, of course, found in _The Knitter's Almanac_
Yarn: Caron's Simply Soft, 1.5 skeins (acrylic! gasp! sorry EZ! next time it'll be wool!)
Needles: US 5 circulars
Modifications: No real modifications, except for the helpful advice of those many who have gone before who suggested casting on an extra stitch on each side of the sleeves (so cast on 8 instead of 7 stitches), and then you can slip this extra stitch each time. This slipped extra stitch will create an easy-to-seam-border for the under-arm seam.
