What was your source for this sewing project? Online Photo or Website Name of website or photo Perfect Zip Bags by Elizabeth Hartman Link to website or photo www.ohfransson.bigcartel.com/product/perfect-zip-bags-pdf-sewing-pattern What are you most proud of? The modifications I made to make them my own. What advice would you give someone starting this project? I made the first one by following the easy-to-follow pattern instructions exactly as written. I thought I would like a more sturdy interfacing and changed up the subsequent bags accordingly. It is a lot of fun adding your own personal touches - patchwork and the like. I will be using this pattern for years to come - I love it!
