Quick and Easy DIYs: Recycled Sweater Box

How do you turn an old sweater into a storage box?

Cover a sturdy cardboard box with a sweater, secure the fabric with hot glue, and optionally add fabric handles. This simple upcycling project turns an unworn sweater and a shipping box into a soft-sided organizer for books, toys, craft supplies, or linens.

Key Takeaways

• Use a sturdy, undamaged cardboard box that fits comfortably inside the sweater.
• Leave 2–3 inches of extra sweater fabric above the box rim so it can fold over the edge.
• Reinforce the bottom seams with packing tape before adding fabric.
• Let hot glue cool and set completely before cutting handle openings or moving the box.
• Handles are optional; skip them for a faster no-sew project.

Sweater Box Instructions

1. Prepare the cardboard box

Choose a cardboard box that fits inside your old sweater without stretching the fabric too tightly. Remove the top flaps to create an open storage bin.

For added durability, apply packing tape across the bottom seams of the box. If you want built-in handles, cut matching handle holes into two opposite sides before attaching the sweater.

2. Test-fit and mark the sweater

Place the box inside the sweater and pull the fabric evenly around all sides. Make sure there is enough material above the top edge of the box to fold inward.

Mark the sweater approximately 2–3 inches above the box rim, then remove the box and cut the sweater along the marked line. The extra fabric will create a clean, covered edge inside the box.

3. Glue the sweater to the box

Place the box back inside the cut sweater. Apply a small amount of hot glue along the bottom edge of the box and press the sweater fabric into place.

Once the bottom is secure, fold the extra sweater material over the top rim and glue it to the inside of the box. Work in small sections to keep the fabric smooth and evenly tensioned.

Safety note: Allow the glue to cool fully before handling the box or cutting fabric around handle holes.

4. Add optional handles

If you cut handle holes into the box, carefully cut matching openings in the sweater fabric after the glue has set.

To make fabric handles, cut four strips from leftover sweater material. Sew or glue two strips together to make each handle stronger, then thread them through the handle holes. Secure the ends with knots or stitches on the inside of the box.

For the quickest version of this DIY, simply skip the handles.

5. Fill and use your storage box

Your recycled sweater box is ready to use. Place it on a shelf, in a closet, on a bookcase, or in a playroom to contain everyday items while adding texture and color to the space.

Good uses include:

• Books and magazines
• Toys and stuffed animals
• Throw blankets or decorative pillows
• Craft materials
• DVDs, games, or media accessories
• Seasonal accessories, such as scarves and gloves

Detailed Findings

A recycled sweater storage box works best when the sweater is slightly larger than the box. A sweater that is too small may stretch unevenly or leave cardboard exposed, while excess fabric is easier to fold inside for a finished edge.

The box itself determines how much weight the organizer can hold. Reinforcing the bottom with tape can help it handle lightweight household items, but cardboard-based organizers are not ideal for heavy objects, wet items, or frequent carrying.

Recycled Sweater Storage Box Checklist

• Choose an old sweater that fits around the cardboard box.
• Select a sturdy cardboard box with no crushed, torn, or weakened sides.
• Remove the box’s top flaps.
• Reinforce the bottom seams with packing tape.
• Decide whether to add handles.
• If adding handles, cut matching holes in two opposite sides of the box.
• Place the box inside the sweater to test fit.
• Mark the sweater about 2–3 inches above the top rim of the box.
• Remove the box and cut the sweater along the marked line.
• Put the box back inside the cut sweater.
• Hot glue the sweater fabric around the bottom edge of the box.
• Fold the extra sweater fabric over the top rim and into the box.
• Hot glue the folded fabric to the inside of the box.
• Let all glue cool and set completely.
• If using handle holes, cut matching openings in the sweater fabric.
• Optional: Cut leftover sweater fabric into strips for handles.
• Optional: Sew or glue two strips together for each stronger handle.
• Optional: Thread handles through the box holes and secure them.
• Fill the finished storage box with lightweight household items.

FAQs

What type of sweater does this project work best?

Medium- to heavyweight sweaters with enough stretches to fit around the box work well. Avoid very thin, fragile, or heavily damaged fabric.

Do I need to sew the sweater onto the box?

No. Hot glue is sufficient for a simple decorative storage box. Sewing is only useful if you want more durable fabric handles.

Can I wash the finished sweater storage box?

No. Because it contains cardboard and hot glue, it should be spot cleaned only with a lightly damp cloth.

How much weight can a recycled sweater box hold?

It depends on the condition and thickness of the cardboard box. Use it primarily for lightweight to moderately light items and avoid overloading the bottom.

Can I make this without handles?

Yes. Handles are optional and skipping them makes this a faster, easier project.
