To make the bags I used vintage label images printed in mirror image onto Avery T-shirt Transfer Paper. I made traditional square corner sacks out of light weight linen. Crafty Daisies has a tutorial for squaring corners. Muslin or flour sack towels would work well too. I filled my sacks with real flour and sugar which gives them the most splendid feel and weight. A tiny bit of flour dust comes through the material when you smack it. I find this irresistible but you can double bag the flour or use plastic pellets if you do not. I closed the top of the bags on my serger. I then folded down the top 1 inch and ran a straight stitch across the serged stitches to make sure the contents stay in the bag. This is a super quick project and would make a fantastic gift with a bowl and beater or felt cookie dough and rolling pin.
