How to Store Leather and Leathercraft Supplies Properly

Quick answer

Store leather flat or loosely rolled in a cool, dark spot at roughly 45–55% relative humidity, away from direct heat and sunlight. Keep tools dry and lightly oiled, seal thread and adhesives in airtight containers, and check every hide and tool every few months. Consistent conditions matter more than any single storage product.

Leather is a natural material, and it keeps changing after you buy it. Too much moisture invites mold and a sour smell; too little dries a hide until it cracks at the bend. The same tension applies to your tools and supplies: damp air rusts steel, heat cooks adhesives, and sunlight fades dyed finishes.

The good news is that leather storage is mostly about consistency, not equipment. Once you set up a dry, dark, stable space and build a short inspection habit, your hides, thread, and tools will stay ready to use instead of turning into a salvage project.

Step 1: Pick the right space and control moisture

Choose an interior closet, cabinet, or shelf that stays cool and out of direct sun. Basements and garages often swing between damp and dry, which is the worst pattern for leather. If your only option is a garage, keep hides inside a closed cabinet or storage bin rather than exposed on open shelving.

Aim for roughly 45–55% relative humidity. A simple hygrometer costs little and tells you whether you need a dehumidifier or a damp sponge in the room. Avoid storing leather directly against concrete floors or exterior walls, since those surfaces wick moisture. A wooden shelf or a plastic pallet keeps air moving underneath.

• Checkpoint: if the room smells musty when you open the door, fix the moisture problem before you put leather back in.
• Never store leather in a sealed plastic bag for long periods; trapped moisture causes mold.

Step 2: Roll or hang hides instead of folding them

Folds create permanent creases and weak lines where the fibers break down over time. Roll large sides and double bends loosely around a cardboard tube, flesh side out, and secure them with a strip of scrap leather or cotton twill tape rather than rubber bands. Rubber bands leave marks and eventually dry out and snap.

For smaller pieces, lay them flat in a drawer with nothing heavy on top. If you must stack, put the heaviest and thickest pieces at the bottom. Suede and other napped leathers should be rolled with the nap facing inward so the surface does not rub against itself.

• Checkpoint: unroll and re-roll stored hides every few months so they do not take a set in one position.
• Label each roll with the tannage, weight, and date so you can rotate older stock first.

Step 3: Separate leather from tools, dyes, and chemicals

Dyes, finishes, adhesives, and solvents give off vapors that can dull hardware and discolor leather over time. Store them in a separate closed cabinet, ideally with a small vent or an open container of baking soda to absorb odors. Never park a bottle of dye on top of a hide.

Tools should live in a dry drawer or roll, not loose in the same bin as leather. Steel tools pick up moisture from leather and from humid air, and a light coat of oil is the simplest protection. Keep a dedicated shelf for hardware and small findings so they do not scratch finished pieces.

• Checkpoint: if you can smell solvent when you open the leather cabinet, the two storage areas are too close together.
• Store needles and small hardware in labeled tins so you are not digging through a mixed bin.

Step 4: Protect thread, lace, and adhesives from heat and light

Thread and lace lose strength when they sit in sunlight or high heat. Keep spools in a closed drawer or opaque box, and keep the original wrapper on the spool so you can read the color and size later. Ritza Silicone Polyester Thread, for example, is a braided polyester with a silicone coating, and keeping it clean and dry preserves that coating for smooth machine stitching.

Adhesives are the most heat-sensitive supply in the shop. Store contact cement and water-based glues per the label, usually between 60–80°F, and bring them to room temperature before use. If a glue has separated, thickened, or smells different, replace it rather than risking a failed bond on a finished project.

• Checkpoint: squeeze a test length of thread before a big project; if it snaps easily, retire the spool.
• Write the purchase date on adhesive containers so you notice when they age out.

Step 5: Build a simple rotation and inspection habit

Once a quarter, open every leather roll, check for mold, insect damage, or drying at the edges, and re-roll in a slightly different position. Wipe tools with a lightly oiled cloth and check for rust spots before they pit the surface. This ten-minute routine catches problems while they are still fixable.

Use older leather first and save newer stock for later. If a hide has started to dry at the edges, a light conditioning can bring it back before you cut into it. Keep a small notebook or a label on each roll with the date it entered storage so rotation is automatic rather than a guess.

• Checkpoint: any hide that feels stiff or shows white bloom should be conditioned and inspected before use.
• Replace desiccant packs in storage bins when they stop absorbing; they lose effectiveness over time.

Your leather storage routine at a glance

1. Set the environment: Choose a cool, dark, interior space at roughly 45–55% relative humidity, off concrete floors and away from exterior walls. Checkpoint: if the space smells musty, fix moisture before storing anything.
2. Roll or lay hides flat: Roll large sides loosely around a tube, flesh side out, and lay small pieces flat without heavy weight on top. Checkpoint: re-roll stored hides every few months to prevent set creases.
3. Separate chemicals and tools: Keep dyes, adhesives, and solvents in a separate closed cabinet; store steel tools dry with a light oil coat. Checkpoint: if you smell solvent near your leather, move one of the storage areas.
4. Protect thread and lace: Keep spools and lace in closed, opaque containers away from heat and sunlight, and retain the original labels. Checkpoint: test a length of thread before a big project; if it snaps, replace it.
5. Inspect and rotate quarterly: Open every roll, check for mold or drying, oil tools, and use older leather first. Checkpoint: condition any hide that feels stiff or shows white bloom before cutting.

Supplies that store well and why it matters

• Ritza Silicone Polyester Thread: A very strong braided 100% polyester thread with a special silicone coating, made by Julius Koch in Germany and designed for mechanical processing and decorative stitching on leather goods. The silicone coating helps thread run smoothly through a machine, so keeping spools clean, dry, and out of sunlight preserves that benefit and prevents fraying or breakage during stitching.
• All-Purpose Needle Pack: Includes curved, glover's, and straight needles, seven needles in all, with sizes ranging from 1 in. (2.54 cm) extra small straight to 3 in. (7.62 cm) extra large straight. Small steel needles rust quickly in humid air, so storing this pack in a dry tin or roll with a light oil wipe keeps every size ready and identifiable when you need it.
• Suede Leather Lace: Leather lace with a 0.13 in. (3.18 mm) width and 25 yards (22.86 meters) length, useful for Native Heritage crafts, buckskinning, Western wear, key chains, and jewelry. Lace tangles and picks up dust easily, so winding it around a card or spool and keeping it in a closed drawer keeps it clean and ready for braiding or decorative work.

Good leather storage is less about buying specialty containers and more about steady conditions and a short quarterly check. Control moisture, roll instead of fold, keep chemicals away from hides, and inspect what you own. Do that, and your leather, thread, and tools will be ready when you are.
