I started working on The Pleated Tote pattern from Jen Giddens. I really like the way she writes her patterns. They are simple and clear of errors. She also includes suggestions for the type of material that would work well and how to customize your bag. I would definitely try some of her other patterns available through Sew, Mama, Sew! and Jen's web site.
For interfacing I am using Pellon 808 Craft Fuse. I am hoping it gives the bag body without being too stiff.
For the exterior of the bag I used Michael Miller's Gray Bird Swing:
For the interior Citron Daisy Flowers, also from Michael Miller:
I still need to iron the bag more, trim some threads and perhaps put some tissue paper or plastic bags inside to full it out for a better picture.
