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!

Supplies:
Warm
fabric of choice- less than half a yard*
Long zipper
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!
Directions:
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.
Sleep Sack Front Pattern
Sleep Sack Back Pattern
Sleep Sack Arm Pattern
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
side.

Now it should look like
this...

Serge or sew the rest
of the center seam shut.

Serge or sew around the
sides and bottom shut, leaving the arm and neck areas
open.

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

Each sleeve should look
like this:

Now you're going to
serge or sew THIS side of the sleeve (where my marker
is)...

to THIS side of the sleep
sack...

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
place.
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
starts.
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.

Optionally, topstitch
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.
