I have been coveting Berroco's Remix Yarn for a while. I think it's perfect for baby items. It's worsted weight (knits up quick - I have commitment issues with needles under a size 5...) made from 100% recycled fibers, and machine washable!!! 30% Nylon + 27% Cotton + 24% Acrylic + 10% Silk + 9% Linen. Perfect for baby leggings! So here's a pattern I made up based on measurements I took from other leggings.
Here's a basic size chart:
Ribbing: 5" unstretched, 10" stretched
Length: 6 inches
Pattern: Knit 1 inch of ribbing on the small needles, 4 inches of leg, and 1 inch of ribbing.
Ribbing: 6" unstretched,
Length: 9 inches
Pattern: Knit 1 inch of ribbing, 7 inches of leg, and 1 inches of ribbing
Child: 7" unstretched,
Length: 12 inches
Pattern: Knit 1 inch of ribbing, 9 inches of leg, and 1 inch of ribbing
Adult: 8" unstretched,
Length: 16 inches
Pattern: Knit 2 inches of ribbing, 12 inches of leg, and 12 inches of ribbing
Size 5 double pointed needles (for top/bottom ribbing)
Size 8 double pointed needles (for leg)
You can use one ball for a single color set of leggings, or multiple colors for stripes and patterns. In this pattern color (A) is "Juniper" and color (B) is "Old Jeans".
Cast on 36 stitches on your size 5 needles in color (A)
Knit in K2/P2 ribbing for the size you want (see size chart above)
Switch to color (B) (if you want to) and size 8 needles for the leg portion (see size chart above)
Switch to color (A) and size 5 needles and knit in K2/P2 for ribbing (see size chart above)
My baby is due in late April so I will show & tell pictures of him wearing them after he's born. Happy Knitting!!!
