Craft supplies come in every shape and size — and that's exactly what makes them hard to organize. A shelf that works great for yarn falls apart when you try to store 12×12 paper in it. A system built for fabric doesn't help much when you need to find a specific skein of thread.

Cube storage is one of the most flexible solutions for mixed craft supplies, but only if you match the right insert to each type of supply. Here's how to do it.

The Core Principle: One Category Per Cube

Before you think about inserts or accessories, start with this rule: one category per cube. Mixed cubes are the enemy of a system that stays organized. When yarn lives with fabric and fabric lives with paper, nothing has a real home and everything ends up in a pile.

Assign each cube a single category and commit to it. The categories don't have to be perfect — they just have to be consistent.

Organizing Paper and Cardstock

12×12 scrapbook paper and cardstock is one of the trickiest craft supplies to store. It's flat, it's heavy when stacked, and it tips over the moment you pull a sheet from the middle of a pile.

The best solution is the Adjustable Shelf Organizer Cube Insert. It adds horizontal shelves inside a cube, turning it into a paper tray — each shelf holds a different color, pattern, or paper type laid flat and separated. The insert is specifically designed to hold 12×12 paper, with an opening width of approximately 12-1/2" to 13" depending on your shelf brand.

You can configure up to 9 shelves per cube using the adjustable pin holes, so you can divide your paper as finely as you need. Cardstock by color, patterned paper by theme, specialty paper on its own shelf — whatever system makes sense for how you work.

This insert works best when your cube shelf is placed against a wall or has a back panel, and it cannot be used vertically.

Organizing Fabric and Rolls

Fabric is bulky, and folded fabric stacks are notoriously unstable. Fat quarters tip. Bolt ends unroll. Interfacing slides around. The problem isn't the fabric — it's that open cubes give it nowhere to go.

The Adjustable Shelf Organizer solves this by creating horizontal shelves where you can stack your fabric by design or color. Each shelf holds a pack of interfacing, fabric bundles or a bundle of fat quarters separated and contained. You can see what you have, pull one piece without disturbing the rest, and put it back just as easily.

You can add or remove shelves based on the height you need.

Organizing Yarn and Fiber

Yarn is round, which means it rolls. An open cube full of yarn skeins looks organized for about five minutes before everything shifts and piles up.

Again, the X Divider Cube Insert is the right tool. Each quadrant holds 2–4 standard worsted-weight skeins upright and separated. You can see every color at a glance and pull one skein without an avalanche. Organize by color, weight, or fiber — whatever matches how you choose yarn for projects.

Organizing Tools and Notions

Scissors, rulers, rotary cutters, seam rippers, stitch markers, bobbins — small tools and notions are best kept in a simple basket or bin inside an open cube. They're too varied in shape and size to benefit from a divider or shelf insert, and a basket lets you grab the whole collection when you need it at your work surface.

Keep tool cubes to one or two. If a basket is overflowing, it's a sign you need to edit your tools, not add more storage.

Organizing Books, Patterns, and Notebooks

Craft books, pattern binders, and notebooks are a natural fit for the Vertical Divider Insert.  Spines facing out makes it easy to find what you need without pulling everything off the shelf.

A Sample Cube Layout for a Craft Room

Here's how a 4×4 Kallax or BHG cube shelf might be organized for a mixed craft room:

• Row 1 (top): Display / finished projects / seasonal supplies
• Row 2: Yarn (X Divider) | Fabric (Adjustable Shelf) | 12×12 paper (Adjustable Shelf) | Pattern books (Vertical Divider)
• Row 3: Rolled Fat quarters (X Divider) | Cardstock by color (Adjustable Shelf) | Tools & notions (basket) | Works in progress (open)
• Row 4 (bottom): Bulk fabric yardage | Paper reams | Backstock supplies | Seasonal overflow

The Result: A Craft Room That Stays Organized

The key to a craft room that stays organized isn't more storage — it's the right storage for each type of supply. Cube shelving with the right inserts gives every category a home that's easy to load, easy to read, and easy to reset.

Start with your biggest pain point — paper that tips, yarn that rolls, fabric that piles — and add an insert there first. Once one cube is working well, the rest of the system tends to follow.

Shop the X Divider Cube Insert for yarn, fabric, and rolls, and the Adjustable Shelf Organizer Cube Insert for paper, fabric, and flat supplies — both custom-sized for Kallax, Better Homes & Gardens, and Threshold/Brightroom cube shelves.
