Recently, I knitted a baby sleep sack to match the Yoda hat I’d made. I love this pattern, because it unbuttons at the bottom for easier diaper changes.
This is the Snug in a Bug Sleep Sack pattern. I used Sensations Sincerely in Grass Green (Weight 4) and US 8 circular needles.
Here is a personal pattern note: When working on the buttoned bottom, it says to BO 36 sts and K the next 36 sts before turning your work. In my personal notes, I wrote that I knit 35 and had 36 sts on the needles, because I had one left from binding off.
This is with a Star Wars wet bag that I made.
This shows how the sleep sack looks with a regular knitted hat (non-Yoda).
This shows how the sleep sack can be unbuttoned.
