I don't have a name for this blanket but I do have instructions on how I made mine!
I apologize for the color disparity, lighting varies in my apartment. This blanket measures 44" x 60" finished.
I used Caron Simply Soft yarn in 6oz sizes.
Orchid: 7 skeins
Baby Brights Ombre: 3 skeins
5.00mm crochet hook
The shell stitch is a multiple of 6 cluster stitch for the way it works up. So if you want your blanket wider, count off 6 chains at a time then add 1 on the end.
1) sc in 1st ch, sk 2 ch, 5 dc in next ch, sk 2 ch, sc in next ch, *sk 2 ch, 5 dc in next ch, sk 2 ch, sc in next ch. Repeat from * across to end of row.
2) ch 3, 2 dc in 1st sc, sk 2 dc, sc in next dc (mid of shell below), sk 2 dc, 5 dc in next sc, *sk 2 dc, sc in next dc, sk 2 dc, 5 dc in sc. Repeat from * across to end of row, 3 dc in turning ch
3) ch 1, sc in 1st st, sk 2 dc, 5 dc in next sc, sk 2 dc, sc in next dc, *sk 2 dc, 5 dc in next sc, sk 2 dc, sc in next dc. Repeat from * to the end of row.
Repeat rows 2 and 3 until desired length.
For the border, I did 2 rows of sc, then I did a (dc, ch 1, sk sc) across for three rows.
Then another 2 rows of sc, followed by one row of dc to finish. I only applied this border to the ends, not the sides.
