I recently purchased the Perfect Zip Bags pattern, by Elizabeth Hartman from Oh Fransson. I was lucky and purchased the PDF pattern when it was on special. It was well worth the money and would still have been, even had I paid the full price.
The bag is fully lined and closes with a zipper. My bag is slightly narrower at the top, than is intended in the pattern, as I didn't have a 7 inch zipper, so had to cut one to size. As I cut the zip a little too short, this meant making the seams wider at the top and so making the bag a slightly different shape. This slight mishap hasn't mattered. I'm still very happy with the overall shape. Depth to the bag is created with darts in the bottom of the bag. The darts make a lovely shaped bag.
Elizabeth's instructions are clear, easy to follow and extremely detailed, with photos for each step of the process. There are three different styles of bag, with variations for each style. I found the method for inserting the zipper different to any I had seen before. The method used in this pattern resulted in the best corners I have ever created in a zippered pouch!!!
I made Style A; a small rounded bottom bag, 4" x 8" x 1½", which was the perfect size to hold a gift card. Next time, I think I'll make the gusseted bottom bag.
