So, I went back to the baby stores to find a size 2T sleep sack. The problem is that they don't seem to sell many of them. My hypothesis is that most children wearing size 2T use those handy little things called "blankets" when they sleep. Interestingly, my little Moonpie hates the things. I have tried covering her with a blanket after she falls into a deep sleep, but this child will throw off the blanket even in deep sleep, and usually wake up as well.
As I was wondering around IKEA (my last stop, and where I get many of my good ideas), I stumbled upon a huge pile of cheapo fleece blankets, and I got an idea. Instead of buying 2 yards of fleece, which would probably also be cheapo quality, why not buy a 6 dollar IKEA blanket and sew my own sleep sack? Yes, why not indeed? So, that's what I did.
Here is the blanket.
I laid out her old sleep sack and drew new pattern pieces on baking paper. I didn't measure, but made them a generous two inches wider and 8 inches longer than the old sleep sack.
It also didn't occur to me to take pictures until after I was done, so I don't have many process pictures. I basically cut out the pieces leaving a roughly half inch seam allowance, sewed in my zipper, then sewed it all up.
I added the flower and reinforced the arm holes and neck hole with a baste stitch, then used my new pinking shears (which I am disproportionately excited about) to give the edges a nice finish. No need to hem fleece. I also added a flap over the top of the zipper to keep it out of Moonpie's sight since she's just discovered that she can open zippers. She can also open velcro, but she doesn't know that it's there, so don't tell her, ok?
She likes this sleep sack, and it's nice and big so she can roll all around in bed without getting stuck or cold and waking up, so I figure this 8 dollar project has bought me hours of sleep. Hooray!
