This is from the top of my head
Size small preemie CO 36-42 Stitches
Size MED-LG Preemie 44-54 sts
NB- 54-62 Sts
Work a Knit 1, Purl 1 across (single rib) or do a double rib (knit 2, purl 2 across) do this for 1 1/2-2 " (All the above is prefrence on what size hat you are making)
After your done with the rib stockenette stitch (knit 1 row, purl 1 row) repeat for 3-4 inches (depending on hat size your making)
you can knit 2 together across (on knit side of hat) then purl the next size
repeat dec row
purl across then cut yarn leaving a long tail put tail on yarn needle weave through stitches left on needle, pull off of needle then pull up tight. Sew up side and weave in ends.
You can do a different type of decrease but this is just a quickie hat pattern I use alot!
Hope it made since lolololol
