If you've been collecting milk cartons and wondering what they're actually good for, this video has your answer — four completely different projects, each one made from a standard Tetra Pak carton, with nothing more exotic than fabric scraps, double-sided tape, a bone folder, and a few brads. The coverage runs from a simple fabric-covered pouch to a structured pocket folder, a no-binding mini album with scored notch inserts, and a flat coin purse you can have finished in under ten minutes.
What we cover
Four milk carton upcycling projects built from a single carton each: a fabric-covered pouch with various closure options, a multi-pocket folder with spine reinforcement, a mini album using scored cardstock notch inserts instead of traditional binding, and a staple-bound coin purse. The video also shows how to cut cartons down into smaller sections for embossed faux-metal embellishments, book corners, tags, and oversized buttons.
What you'll learn
How to prepare and flatten milk cartons for crafting — washing, air drying, and pressing them flat under a heavy weight so they're workable before you start cutting.
How to cut and shape a pouch from a whole milk carton, including:
- Deciding flap depth so it closes without swallowing too much interior space
- Finding and turning the internal seam away from the visible side
- Trimming a triangular envelope-style flap
How to cover shiny Tetra Pak surfaces with fabric, including:
- Sanding the surface before applying PVA or paint so it doesn't peel
- Using heavy-duty double-sided tape (carpet tape or foil tape) to create a pre-adhered fabric that applies cleanly
- Applying glue before washi tape on any shiny surface
- DIY fabric-backed tape using strips of whatever double-sided tape you have on hand
Closure options for pouches and folders, including:
- Brad-and-elastic loop
- Brad-and-string with decorative beads
- Velcro or hook-and-loop dots
- Snap buttons applied with a snap gun
- Strong magnets (with the caveat that they need to be pressed flat under significant weight while the bond sets)
- Elastic lace or a repurposed headband
- Picture-hanger hooks used as a clasp, threaded through with a brad
How to build a multi-pocket folder from four to six cartons, including:
- Trimming all carton pieces to identical height using the first one as a template, or stacking and clipping them together to cut in one pass
- Constructing and reinforcing the spine from a milk carton with added cereal-box layers
- Covering the spine fabric in sections to get two distinct panels rather than one uniform wrap
- Only covering the visible sides of the inner pouches — the unseen surfaces stay bare
- Attaching pouches in order, aligning each to the one before
How to reinforce a milk carton spine so it doesn't flex inward or outward — cutting thin strips of cereal box cardboard slightly narrower than the inner spine width and laminating them inside and out.
How to make scored notch inserts for a no-binding mini album, including:
- Scoring peaks and valleys in cardstock at half-inch and quarter-inch intervals
- Gluing only the peaks (the notches), leaving the valleys as empty hinged space
- Centering the assembled insert on the inner spine panel before gluing
- Tapering the inner spine piece so it doesn't overhang the cover edge
How to add pages to a notch-insert album, including:
- Single pages that open flat (glued to one face of the notch)
- Closed pockets (glued along the bottom and side edges)
- Hand-sewn dividers to create two pockets from a single page
- Using file folder offcuts as sturdy, print-free page stock
How to make a coin purse or mini wallet from a flattened carton, including:
- Folding in side gussets before cutting
- Stapling the sides closed and hiding the staples under a fabric cover
- Rounding or trimming the flap edges to neaten the shape
How to use cut-down milk carton sections as embellishments, including:
- Running pieces through an embossing folder for faux-metal texture
- Cutting embossed sections into book corners, tags, dangles, and mini envelopes
- Punching two holes in a circle to make an oversized faux button
Tips & gotchas
Flatten before you start. If you're saving cartons for a future project, open and flatten them immediately and stack them under something heavy until you're ready. A carton that dries folded will fight you the whole time you're trying to work with it.
The shiny surface is the main obstacle. PVA, paint, and even washi tape all want to peel off an unprepped carton. Sand the surface first — and if you're painting, apply a coat of gesso before your colour. Skipping this step is the most common reason things fall apart later. The same applies to washi tape: apply a layer of glue first, then press the tape on top.
Magnets need commitment. If you use them as closures, they have to be strong, and the carton has to be pressed completely flat under a heavy weight for a long time before the bond holds. A light magnet or a quick set will just pop back up.
Score before you fold cardstock for notch inserts. The half-inch/quarter-inch scoring pattern only works cleanly if the lines are scored rather than just bent. A scoreboard is ideal, but a ruler and a bone folder get you there without one.
Do your embellishments before gluing pages in. Working on flat pieces is dramatically easier than trying to add detail once everything is assembled and the pages are locked in.
On the mini album: apply the spine closure hardware before the inner cover panel goes down. Thread the brad or hook through the cover first, then glue the inner panel over the back of it. Once that panel is down, you can't get to the hardware without damaging something.
When gluing the inner spine insert, keep the book open while the glue dries. Gluing it with the book closed can lock the hinge in the wrong position. Open it, let it set, then proceed.
Double-sided tape grips immediately — which is exactly what you want for fabric corners, but it means you only get one chance to place something. For the inner spine insert, use PVA or fabric glue instead so you have a few seconds to adjust the position before it locks.
A stack of flattened Tetra Pak in your craft room stops being recycling and starts being raw material — spines, pockets, covers, embellishments. The embossed faux-metal pieces in particular open up a whole separate direction: book corners, dangles, tags, and closures that look like they came from a supply shop rather than your kitchen bin. That thread is probably worth its own video.
