Cowboy Outlaw Presser Foot: Sewing Thick Leather Seams

Quick answer

Use the Cowboy Outlaw presser foot that matches your seam side—right toe for right-side curves, left toe for left-side curves—and adjust presser foot pressure and stitch length before you start. Test on scrap leather first to confirm the foot clears thick seams without dragging.

Step-by-step: sewing thick leather seams with the Outlaw presser foot

1. Choose the correct toe for your seam: Select the Right Toe (3786-05) if the bulk of your seam sits to the left of the needle or you're following a right-hand curve. Select the Left Toe (3786-04) for the opposite orientation. Common mistake: using the toe that matches your dominant hand rather than the seam's geometry. Lay your leather flat and note which side the thickest overlap falls on before choosing the toe.
2. Install the foot and set presser foot pressure: Attach the chosen presser foot to your Cowboy Outlaw Sewing Machine. Reduce presser foot pressure slightly from your normal setting so the foot can ride over thick seams without compressing the leather. Common mistake: leaving pressure at a high setting, which can cause the foot to dig in and stall the feed. Start with lower pressure and increase only if the leather lifts with the needle.
3. Adjust stitch length for thick material: Increase stitch length to at least 4–5 stitches per inch for thick leather seams. Longer stitches reduce the chance of the needle deflecting and help the feed dogs move the work consistently. Common mistake: using a short stitch length meant for garment leather, which can cause skipped stitches or broken thread. If stitches look crowded, lengthen them before changing tension.
4. Test on scrap leather of the same thickness: Sew a test seam on a scrap piece that matches your project's thickness and layer count. Check that the presser foot clears the seam, the stitches are even, and the leather feeds without puckering. Common mistake: skipping the test and discovering tension problems on the final piece. Keep a labeled scrap of each leather you use for quick tension checks.
5. Sew slowly over the thickest point: Approach thick seam intersections at slow speed—turn the handwheel by hand if needed—so the presser foot can rise over the bulk without jamming. Common mistake: running the machine at full speed, which can bend the needle or force the foot off track. If the foot lifts more than 1/8 inch, stop and hand-crank through the section.
6. Check seam quality and adjust as needed: After the first seam, inspect the stitch formation on both sides. If loops appear on the bottom, increase top tension slightly; if the top thread pulls through, decrease it. Common mistake: adjusting tension without re-testing on scrap, which can lead to a chain of tension errors. Make one tension change at a time and re-test on scrap before sewing the project.
