Rounds 11-15, changing colors, & the decrease stitch

Now that you've got the hang of crocheting, let's learn how to change colors and do the decrease stitch. First, here's a preview of what we're going to do in pattern speak:

Round 11: 40 sc, dec (41)
Round 12: (switch to white) dec, 17 sc, 2 dec, 14 sc, 2 dec (36)
Round 13: 2 dec, 11 sc, 4 dec, 13 sc (30)
Round 14: [3 sc, dec] x 6 (24)
Round 15: [2 sc, dec] x 6 (18)
