This pattern is different than a regular sewing pattern and you need to be somewhat of a sewing free spirit and have solid sewing experience for this one. You can read the full description here. If you've made this bag and enjoyed sewing this way, leave a comment below.
Besides just using one main pattern piece, the next best thing about this pattern is you can use this technique to easily make all sorts of sizes. This bag is the third size I've made and blog posts for two other custom sizes can be found here and here.
The last page of the text instructions in the pattern has instructions for making this in custom sizes. Here are the measurements for the pattern piece and the where the divisions are placed for this one:
- 10" wide (25cm)
- 6" high (15cm)
- C is at 2" (51mm)
- A is at 1.25" (32mm)
- box bottom 1.5" (38mm)
