I'm on the 13th repeat of Backyard Leaves, but left off to finish the Tigger sweater for my son (knit and attach ears--that's all that was left).
The occasion? He finally lost his first tooth! He was so proud. Unfortunately, his belief in the tooth fairy has already fled, so he asked me to put something under his pillow. "Or if it's a toy or something, Mom, put it right here by my bed, OK?"
He has a Sacagawea dollar under his pillow and a finished Tigger sweater next to it.
(The ears turned out cute. I cast on 5 stitches, kfb at each RS row end for 2 rows, then started short-row shaping on the next WS row: I purled across 5 [of 9] stitches, wrapped the next stitch and turned, repeating for maybe 4 rows. k2tog at each end of RS rows twice, then bound off all. They're nicely cupped.)
