Here is a very easy FREE pattern I have used for 2 baby blankets and one large afghan:
Diagonal Pattern Baby Blanket
[/SIZE]Lion Brand® Homespun® GAUGE:[INDENT]9 sts and 18 rows = 4 inches (10 cm) in garter stitch (knit every row) BE SURE TO CHECK YOUR GAUGE. When you match the gauge in a pattern, your project will be the size specified in the pattern and the materials specified in the pattern will be sufficient. If it takes you less stitches and rows to make a 4 in. [10 cm] square, try using a smaller size hook or needles; if more stitches and rows, try a larger size hook or needles.[/INDENT]
