This s a small baby blanket (or carrage cover). I used left over double knitting yarn (mostly Snuggly) but you can use any weight yarn, just adjust the needle size. I used size 5 US (straight) with the DK yarn.
Here's the pattern:
This is knitted in garter stitch.
Cast on 4
Knit across
This begins the increase rows.
Row 1: Knit one (K1), Yarn over needle (YO), Knit across then turn
Repeat Row 1 until you have 40 stitches.
Now you'll begin the decrease rows.
Row 1: Knit two together, Yarn over needle, Knit two together, Knit across.
Repeat decrease row until you have 4 stitches remaining.
Cast off.
