Okay... here is my tutorial. I am very visually oriented, so I apologize for the mass amount of pictures. This is my safety net, provided my written instructions are confusing.
I'm using leftover pink & brown yarn & a size I/9 (5.50mm) hook.
"Special" Stitch: shell= 6 treble crochets in stitch specified.
Dc in 4th ch from hook & across. (13 dc) Ch 3 & turn.
Dc in same dc as ch 3 & across (14 dc). Ch 3 & turn.
Dc in each dc across (excluding the dc w/ the ch 3 as in previous row). (13 dc)
Here's where it gets a lil tricky for me to explain, so here come the multitude of pictures.
Now we are going to put a shell on the side of the 3 rows. Slip stitch here:
Quality is a lil crappy, I'm sorry.
The shell consists of 6 treble crochets. They go here:
Once you have completed the shell, slip stitch it to the first dc of your beginning row:
Skip 2 dc & put shell in 4th dc, as shown here:
Then, skip 3 dc & sl st here:
Skip 2 dc & put shell in next dc. (don't have a photo sorry, but you'll be able to get the idea from the next one)
Slip stitch around last dc of row:
Put another shell around the dc of the middle row, like you did on the first side (no photo).
Slip stitch in top of "dc of last row" (otherwise known as the ch 3 from the 3rd row...just slip stitch in top of ch 3):
Continue with 2 more shells as stated above. Fasten off.
Now, to attach the cupcake bottom.
Join brown w/ slip stitch in any corner of your "puff" (in the same place where you slip stitched down one of your side puffs).
Ch 3 & dc in same place as where you slip stitched to join.
Skip 1 treble crochet of the shell & sc across the next 4 treble crochets. (once again, I apologize for the crappy photo quality)
Skip last treble crochet & dc in space between shells where you slip stitched down your shell.
Skip 1 treble crochet & sc in next 4 treble crochets of 2nd shell.
Skip last treble crochet of 2nd shell & put 2 dc in corner.
Ch 2 & turn. Hdc across, but do NOT hdc in the top of the ch 3 from the previous row. (11 hdc, do not count ch 2).
Ch 2 & turn. Hdc across, do NOT hdc in top of ch 2 from previous row. (10 hdc, do not count ch 2).
Ch 2 & turn. Hdc across, do NOT hdc in top of ch 2 from previous row. (9 hdc, do not count ch 2).
Ch 2 & turn. Hdc across, do NOT hdc in top of ch 2 from previous row. (8 hdc, do not count ch 2). Fasten off.
There you go! There's my first ever tutorial! Sorry about all of the pictures. I guess I like to be very thorough.
