The Half Square Triangle Pouch is a flat square-shaped quilted pouch with a zipper running diagonally across the front. Finished size is 10cm (4") square. It is tiny but opens wide and holds more than it looks. Using this pattern, you will be able to make two HST pouches at the same time, so it is perfect for gift giving. You can keep one for yourself! (Sometimes after I give away a handmade gift, I miss it and wished I made 1 extra for myself. Is it just me?) Here is the trick to create this clean and simple look---It's one continuous zipper tape. For this tutorial I used zippers called "Free Style Fastener" which comes 120cm single zipper tapes and pulls separately. They are readily available in Japan and come in 2 sizes, 2 types of pulls and loads of colors. You can find them online but if you can't find this kind of zipper, then any long nylon coil zipper will work. You separate a zipper into 2 tapes and 1 pull. Just cut off the zipper stop at the both ends and slide the zipper pull out. Ta Da! You have a one-sided zipper to use! NOTE: There are some types of zippers (such as metal and invisible zippers) will not work. Also, you will have to use 1 extra zipper pull so you can make your 2nd pouch. They are hardly seen at a local sewing store but you can buy them online. If it is not easy for you to get 1 extra zipper pull, then just buy 2 zippers so you will have enough pulls for this project.
