I used the book Handmade Home by Amanda Soule Blake to make them. There were challenging parts, such as dealing with the blasted bobbin, and figuring out how to make button holes (the machine just does it FOR you! Even my ancient one!) I wanted to make a bag to replace the above lovely plastic one, which has been my place to put the multitude of bibs and washcloths that clean up mealtimes. Babies have a way of exponentially increasing one's laundry, no?
This is the one I made! I think it looks much better. I had some sturdy canvas material, which I figured would hold up well. I didn't make the cloth balls hanging down that the book suggests, but I did make a pocket on the front. For color. And I used hem tape that I found at a thrift store (5 packs/$.26!) for the straps and drawstring.
