To create this pattern, I began with a short starting chain and figured the pattern design out as I went along, writing the instructions for this oval in a way that allows for you to continue the piece, to result in any size that you want.
In this pattern, a shell = (2 dc, ch 2, 2 dc) all made in one same place
Starting Chain: Chain 12.
Rnd 1: Working in back loop only of each chain, sc in 2nd ch from hook, sc in ea of next 9 chs. Make 3 sc in next ch, then working along other side of chain, sc in remaining loops of ea of next 9 chs, until one chain remains, then make 2 sc in last chain,
join with sl st in first sc.
Rnd 2: ch 1, sc in same place as sl st just made, * ch 1, skip next sc, (2 dc, ch 2, 2 dc) in next sc, ch 1, skip next 2 sc,
sc in next sc, ch 1, skip next 2 sc, (2 dc, ch 2, 2 dc) in next sc,
Rnd 3: ch 3 (counts as first dc), dc in same place as ch-3 just made, * skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell, 2 dc in next sc, skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell, 2 dc in next sc,
Rnd 4: ch 3 (counts as first dc), 2 dc in next dc, * skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell, dc in ea of next 2 dc, skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell, 2 dc in next dc, dc in next dc,
Rnd 5: ch 3 (counts as first dc), dc in next dc, 2 dc in next dc, * skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell, dc in ea of next 2 dc, skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell, 2 dc in next dc,

Rnd 6: ch 3 (counts as first dc), * dc in ea of next 2 dc, 2 dc in next dc, skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell, dc in ea of next 2 dc, skip next 2 dc of shell,

Rnd 8: ch 3 (counts as first dc), * dc in ea dc until there is one dc left before the next shell, make 2 dc in that last dc (before the shell), then skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell, dc in ea of next 2 dc, skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell, 2 dc in next dc, dc in ea dc until there is one dc left before the next shell, make 2 dc in that last dc (before the shell), then skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell, 2 dc in next dc, dc in ea dc until there is one dc left before the next shell, make 2 dc in that last dc (before the shell), then skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell, 2 dc in next dc, dc in ea dc until there is one dc left before the next shell, make 2 dc in that last dc (before the shell), then skip next 2 dc of shell, (2 dc, ch 2, 2 dc) in ch-2 sp, skip next 2 dc of shell **, 2 dc in next dc, then repeat the directions between * and ** once, then dc in next dc, then sl st in top of the beginning ch-3 of this round.
Additional Rounds: Repeat Rnd 8 until you have the size that you want.
Last Round: ch 1, sc in same place as sl st just made, sc in ea dc until you reach the next ch-2 (in the center of a shell), 2 sc in that ch-2 sp, sc in next dc, dc in ea of next 4 dc, sc in next dc, 2 sc in ch-2 sp, (sc in ea dc until you reach the next ch-2, 2 sc in that ch-2 sp) 4 times, sc in next dc, dc in ea of next 4 dc, sc in next dc, 2 sc in ch-2 sp, (sc in ea dc until you reach the next ch-2, 2 sc in that ch-2 sp) 3 times, sc in ea of next 3 dc, sl st in beginning sc of this round.
