I use New Stitch a Day to learn new knitting stitches.
Here is the 'Little Pyramid Stitch' which I have been knitting this weekend.
I have added photos of each row to help when I make mistakes!
Row 1: k5, *p1, k5; rep from * to end.
Row 2: k1, *p3, k3; rep from * end with p3, k1.
Row 3: p2, *k1, p5; rep from * end with k1, p2.
Row 4: p2, *k1, p5; rep from * end with k1, p2.
Row 5: k1, *p3, k3; rep from * end with p3, k1.
Row 6: k5, *p1, k5; rep from * to end.
Repeat these 6 rows until you have reached your desired length.
