"My little monster loves sleeping bags, and won't go to bed without one, but I only have warm winter ones and haven't been able to find cooler ones for the spring and summer. I was wondering if your crafty talents would be able to come up with something."
So, this is what I came up with...
I used a light blue muslin fabric with a red knit trim.
I made it so that it's roomy in the legs as Bailey's a fairly active sleeper.

It's a very simple design. I decided to use a zipper at the front. 
The muslin fabric was slightly fiddly to sew with as it kept moving around. I'm going to use a light-weight cotton for the next one.
