Sew Your Own Baby Sleep Sack!
When our little guy outgrew
his 0-9 mo sleep sack at the age of six months, I came up
with this pattern so I could make him a sleep sack that's
plenty warm and plenty long!
Warm fabric of choice- less than half a yard*
ribbing for neck and cuffs
*I'm not sure how much it took since I already had my fabric on hand. Just print out the pattern pieces and take them with you when you buy your fabric!
Print and cut out the pattern pieces (below). Take them with you when you buy your fabric. This pattern is the next size up after the 0-9 mo sleep sacks. You could scale it down a bit for a smaller baby by printing it at 75% size.
A note on printing: this is a scan of a piece of printer paper- 8 1/2 inches wide. So your printout should fill up the whole paper. After clicking my link, you'll see the pattern piece online, but it's scaled down. You'll probably need to right click and save the photo to your computer. Then open it up and print it full size.
Cut out your pieces, paying attention to where the pattern pieces are to be placed on an edge or on a fold. The front and back end with arrows going down so you can determine the length you want. Mine is about 29 inches from the neckline to the bottom seam which allows for plenty of room for little legs to waller around.
Pin your zipper in
place along the center edge of the front piece. Serge or
sew the zipper in place.
Repeat on the other
Now it should look like

Fold each sleeve in
half. Serge or sew this side (that my fabric marker is
laying against) of the sleeve together. Repeat on the

You'll definitely want to
pin it in place. After you do, then flip it right side out to
make sure that you have it on right. Then serge or sew it in
Now the sleep sack should look like this (it's inside out)... with only the neck hole and cuffs unfinished:
Cut a strip of ribbing, fold it in half, then pin it to the neck line, like this...
The raw edges should be
together, and the ribbing should curve off where the zipper
Serge or sew it in place. It should look like this:
Cut two more strips of ribbing for your cuffs. Mine were 1 1/2 inches by 8 inches.
Fold it in half short end to short end, and sew or serge the short ends together.
Re-fold the ribbing the opposite way, right side out / seam side in. It should look like a cuff now:
Attach a cuff to each sleeve (like you did the neckline) and sew or serge in place.
along the edge of the ribbing to keep it in place.
Optionally, you can add
on a little tab (it's drawn onto the pattern) to snap
down at the top and cover up the zipper. I just ended up
not doing that part.
Insert cuddly baby.
Last, if you decided to
do this project yourself, please send me a photo of your
little one happily using their sleepsack, (or if your
baby hasn't arrived yet, just a picture of the finished
sleep sack is fine too!) along with your name and what
state you're from! I've recently decided to start
featuring my readers' finished results.
