Sew a leather tool portfolio from the Tandy paper pattern. Follow these steps to cut, mark, and assemble a 13 x 7 x 1 in. organizer that keeps your leathercraft tools protected and ready.

Quick answer

Use the Tandy Tool Portfolio Paper Pattern to cut your leather pieces exactly, then sew a simple wrap that holds your tools without scratching them. The pattern gives you full-scale pieces and a material list, so you can focus on clean cutting and stitching.

Why a paper pattern makes tool storage easier

A paper pattern removes guesswork from sizing pockets and folds. The Tool Portfolio Paper Pattern includes full-scale pieces, a material list, and an assembly overview, so you can replicate a proven layout instead of designing from scratch. That matters for leathercraft tool storage because small differences in pocket depth or fold lines can make a portfolio too tight or too loose.

The finished portfolio measures 13 x 7 x 1 in. (33 x 17.8 x 2.5 cm), a compact size that fits most bench tools. The pattern recommends 3 to 4 oz semi-firm to semi-soft leather, which balances structure with flexibility. If you choose a different weight, expect the fold lines and pocket stretch to behave differently.

Leather choice and preparation trade-offs

The recommended 3 to 4 oz leather is easy to cut and sew on most machines or by hand, but it may not hold a rigid shape over time. Heavier leather adds durability but can be harder to turn at corners and may require a larger needle and stronger thread. The pattern does not specify a thread type or stitch length, so test on scrap first.

Before cutting, check the pattern pieces against your actual tools. The pattern is designed for a general set, but your tools may be longer or thicker. Adjust pocket widths on a copy of the paper pattern rather than on the final leather.

Common mistakes to avoid when sewing a leather tool portfolio

Skipping a test fit is the most common error. Paper patterns are accurate, but leather has thickness and stretch. Always cut a scrap pocket and test your tool fit before committing to the full piece. Also, mark fold lines on the flesh side with an awl or chalk, not a pen that may bleed through.

Another mistake is sewing pockets too tight. Leather stretches slightly with use, but a pocket that is too tight from the start can be frustrating. Allow a little ease, especially for tools with handles or textured grips.

Steps to sew your leather tool portfolio

Cut and prepare the pattern: Trace each paper pattern piece onto your leather using an awl or scratch awl, keeping the grain direction consistent. Cut just outside the line and sand edges smooth. Checkpoint: label each piece with chalk to avoid mixing up similar shapes. Cut all pieces before sewing so you can chain-step the assembly.
Mark fold and stitch lines: Use a wing divider or stitching groover to mark fold lines and stitch lines on the flesh side. Set the divider to the pattern's seam allowance (typically 1/8 to 1/4 inch) and test on scrap. Checkpoint: fold the leather along each marked line to ensure it bends cleanly before stitching. Marking both sides of the leather prevents twisted pockets.
Sew the pockets and slots: Stitch pocket dividers first, backstitching at each end. Use a lock stitch or backstitch to secure. Checkpoint: slide a tool into each slot as you go to confirm fit; adjust before sewing the outer seam. Sew pockets before assembling the outer shell for easier handling.
Assemble the portfolio body: Align the outer shell and pocket panel, then sew around the perimeter with a 1/8-inch seam allowance. Leave a 3-inch opening for turning if you are lining the portfolio. Checkpoint: clip corners diagonally before turning to reduce bulk. Reinforce the top edge with a second stitch line for durability.
Finish edges and add closure: Burnish or paint edges, then install a closure such as a strap, snap, or tie. The pattern does not include closure hardware, so choose based on your tools. Checkpoint: test the closure with the portfolio fully loaded to ensure it holds securely. Break in the leather by folding and unfolding a few times before first use.
