The pattern for the scalloped edge: here.
I had to make a few adjustments, as I was off by a few stitches after the treble crochet rows. For the arm hole widths, I chained 18 and stitched into the 19th stitch, and I only had 6 sets and two half-sets of bobbles for the backside. I made a scalloped edge along the bottom.
Front edges: 1 row of half double crochet (wrong side facing out), 1 row of single crochet (back loop only, right side facing out).
Button-holes: chain 2, single crochet 2
Collar: 1 row of single crochet, another row of single crochet (decrease after every 5 stitches, front loop only).
Collar corner (row 1): in corner hole {2 half double crochet on side that is closest to front, chain 3, 1 single crochet on side that is closest to neckline}
Collar corner (row 2): {single crochet, chain 1, single crochet}
The silver buttons were originally from Kmart (3/$0.90), but I got them at a thrift store for 3/$0.25.
This item may be available at the craft show. I'm still quite attached to it. If I knew it would fit my newest baby niece, I would give to her, but I think it would be too small for her already. I'm quite tempted to keep it for my own (yet-to-be-conceived) baby...
