For a baby blanket size 36" x 36":
I used one pound skein Red Heart Giant and size 9 29" circular needle.
Use whatever yarn you wish with an appropriate size needle.
This blanket is knit on the bias so gauge isn't all that important. Just keep knitting until the side is as long as you want the blanket to be and then begin decreasing blocks for the second half of the blanket.
Pattern:
Cast on 6 sts;
Knit 10 rows;
(Creates first garter stitch block)
At beginning of next row (row 11) (RS):
Cast on 6 sts;
K 12;
Row 12:
Cast on 6 sts;
K6, P6, K6 (18 sts)
Row 13:
K18
Row 14:
K6, P6, K6;
Repeat Row 13 and 14 3 times (20 rows total)
(Creates second section of blocks)
At beginning of next row (row 21) (RS):
Cast on 6 sts;
K12, P6, K6;
Row 22
Cast on 6 sts;
K6, *P6, K6* x2;(30 sts)
Row 23
K12, P6, k12;
Row 24
K6 *P6, K6* x2;
Repeat Row 23 and 24 3 times (30 rows total)
(Creates third section of blocks)
Continue in this manner, with garter stitch block on each end and alternating stocking-stitch and reverse stocking-stitch for each block section until the side of the blanket is as long as you wish.
Then begin the decrease blocks.
Decrease block section:
First row:
Bind off 6 stitches (The last stitch left on the needle counts as the first K stitch)
*K6, P6* across, ending K12;
Second row:
Bind off 6 stitches (The last stitch left on the needle counts as the first K stitch)
K6 then continue across in pattern ending K6;
Continue knitting this section in pattern until 10 rows are complete.
Every 10 rows, bind off one more block on each end of the section and keep in pattern per the diagram.
