100% human-made patterns. Every design is created, drafted, prototyped, built, and tested by me. No AI-generated patterns. I create original PDF patterns for hand-stitched leather bags, backpacks, accessories, home decor, corsets, hats, and other leather projects. I have been doing leatherwork since 2016 after working as a graphic designer since 1998.

ABOUT THE PATTERN:

This sling represents a Giant Deep Sea Isopod, and it's absolutely not an insect, beetle, cockroach or anything else, it's a beautiful marine crustacean. Some may refer to it as a pill bug or roly poly which are its terrestrial relatives.

This project is for more experienced leather crafters as it may be somewhat scary for a beginner. The pattern consists of 86 pieces and would take about 3-5 days to assemble, depending on how fast you work.

The pattern has stitching holes marked for 5mm stitching irons, but on some pieces the stitch length may vary slightly to fit in confined spaces, obtain the correct shape and avoid unnecessary tension.
