I don't know about you... but my baby [and I use that term loosely] has decided to grow up on me!
At 5 months old he is already 17lbs 4.6 oz and 28inches (or better) long!
Compare that to his birth stats of 10lbs 1oz (yep big baby) and 20 inches long.
It makes me sad that he is growing up so quick!
As a first time mom I just knew that I could NEVER live without what I can a sleepy sack. Especially not after all the horror stories I heard about babies covering their heads with blankets in the night! Blankets in my kids crib? Psh! I think not!
I purchased a Halo [you didn't see that] Sleep Sack and was amazed! Not only did it swaddle but it kept him warm! GO SLEEP SACK!
So in true mommy crafty-ness I got right on it procrastinated!
So here goes!
Disclaimer: I am not claiming to be good at this tutorial thing so if my directions completely bite just comment or email me and I will see what I can do to change it up! :D
And I apologize for the crap-tastic pictures... my camera doesn't like me!
What you need:
-2 t shirts or one REALLY long t shirt
-Medium width velcro (half of the length of your child) or a zipper
-shirt with no sleeves that fits your child or is a teensy bit big
-your trusty sewing machine
-patience
Here goes:
First measure how long your kiddo is and add several inches. My son is 28 inches head to toe so I made this 32 inches long.Than you gather your t-shirts and your child's sleeveless .

Cut your shirt that you want for the main color up the sides

We are going to use the collar that is already there since it is ribbing and it will have a nice finish (and stretch since your making this for your LO to grow into) So put your childs shirt to the neckline and use a fabric pencil or marker to trace.
When drawing the pattern make it flow out slightly like a dress.
This piece should be your child's height minus 2 inches.
(don't worry we will add those inches and than some back later)

This is what you should have (if you didn't mess up you will have just one drawing)

Cut it out through ONE thickness of the shirt because remember the back neckline is different from the front!

(remember to cut out ONCE SIDE AT A TIME because the back necline must be higher than the front! )
[now repeat those last couple of steps for the back of the sleep sack]

The neckline should look like this!

Remember those two inches we took away? Add those plus the extra you added when calculating and cut out a "bottom" for your sack.
When cutting remember that the sack flows like a dress so it is a good idea to lay your sack on your shirt to cut.
(I.e. my child is 28 inches tall.. I made this 32 inches long. So my bottom panel would be 6 inches long)

Like so...
Than round out the corners (it just looks good)

Now we are moving onto our trusty sewing machine!
