There's nothing easier to knit than a rectangle of Garter Stitch, but there are some things you can do with such projects beyond just knitting scarves. If there are any little feet in your vicinity you can keep them warm with some little slippers.
Speaking from experience, these work best for kids who are either too little to pull things off their feet or big enough to not do so. Kids who immediately take off their socks and put them in their mouths will have these off their feet before you can even put them on. Fair warning.
- small amount of bulky weight wool or other fiber of your choice (mine, in the second size listed, used about 34 yards of Knit Picks Wool of the Andes Bulky)
- one pair size 10 US (6 mm) knitting needles
- tape measure, scissors, yarn needle
about 3 stitches and 6 rows per inch in Garter Stitch. Gauge is not incredibly critical, particularly if you're making them a custom size for your little one.
Slipper is sized roughly to fit a newborn (3-6 months, 6-12 months, 12 months plus), with a finished size of about 5 (5.5, 6, 6.5) inches long. Pattern gives directions for the smallest size first with larger sizes in parentheses. Kids' feet vary widely in size so the best way to fit is to measure the child in question's foot. The finished slipper should be the same width (cast on stitches) as the foot measures around, and the length should be 1.5 inches longer than the child's foot.
- Cast on 12 (14, 16, 18) stitches.
- Work in Garter Stitch (knit every row) for 5 (5.5, 6, 6.5) inches.
- Bind off.
- Fold piece in half lengthwise and sew up the bind off edge to be the back of the slipper.
- Sew up the cast on edge and about 2 inches across the top of the foot to help hold the slipper on the foot.
Make a second slipper the same as the first.
