DIY tutorial for knit fabric pajama pants for kids and babies

Hey y’all, we’re back with part 2 of this pajama set today showing how to sew stretchy pajama pants for kids and babies. These close fitting pants are very similar to leggings with cuffs on the bottoms. They’re also great as another layer under jeans when it’s really cold. See how I made the raglan style tops last week in this post.

Supplies for the whole pajama set, including the top, are listed below.
- 1 1/2 yards of knit fabric. Because this is so fitted, you want to make sure that the fabric has 4 way stretch; this is part of why the Riley Blake knits are perfect since they have 4 way stretch and 5% spandex.
- 1/4 yard of rib knit fabric for the cuffs and neckband – fabric should have at least 80% stretch for the neckline (that means you can stretch a 10 inch piece to 18 inches). You could use the same fabric as the body IF it has good stretch and recovery.
- 19 inches of 1 inch wide elastic
- The pattern (see below)
The free pattern is in size 4T. If you need to make the pattern bigger or smaller, check out this post. To get it, click your preferred option below to get the free pattern only as a newsletter subscriber, or you can buy the full digital pattern in sizes 18M through 8 using the button below.
