I’m still new at this knitting thing, and haven’t ever done a chart before… but I want to knit up some little sleep sacks for my soon-to-be twin godchildren. I think I can throw together the sacks on my own, but I wanted to put a picture on the front of each one, to add some interest. I thought I would do a heart for the girl, and a star for the boy. Does anyone have any idea where I could find charts for these? Or any other baby-type ideas? Thanks! 
Here’s some to look at

the first stitch and bitch book will show you how to design your own charts, oryou could do it yourself with some graph paper and trial-and-error.
check some embroidery books or site as well.
Thanks!
