The Craft Closet
The STEM Studio's equivalent of cardboard and duct tape. Glitter, pipe cleaners, googly eyes - the everyday supplies that turn a Makey Makey project into a memorable one.
The makerspace has its cardboard and duct tape. The STEM Studio has its craft closet. Both are Stage 0 - the foundational layer of consumables a space needs before any kit earns its spot. The difference is that over on the makerspace page, glitter is on the "deliberately not on this list" line. Here, it is the point.
This page is a bulk-buying guide. A well-stocked craft closet serves a STEM Studio for a full school year on $200-$400, and turns every Makey Makey project, every robot decoration session, every book-report interactive display into something kids actually want to take home.
Short version
Craft basics: bulk glitter, googly eyes, pom-poms, pipe cleaners, feathers, stickers.
Sorting + counting: beans, pasta, buttons, bottle caps.
Paper + fabric: construction paper, foam sheets, felt, tissue paper, yarn.
Storage: labeled containers, sorting trays, a closet with a door.
Craft Basics
The decorative materials that let a kid finish a project and call it done.
Rule of thumb: buy bulk from a craft supplier, not retail from Target. A Target sticker pack costs $3 for 100 stickers. The same stickers bulk-purchased from Oriental Trading or S&S Worldwide run $15 for 1,500. For a STEM Studio running weekly rotations, bulk is not optional.
Glitter (bulk shakers, not tubes)
Shaker bottles are safer than pinch-loose glitter for elementary use - kids can distribute a controlled amount without dumping the whole jar. Get a pack with 12+ colors from a craft-education supplier (S&S Worldwide, Oriental Trading, Discount School Supply). Skip single-tube Target glitter.
Googly eyes (wiggle eyes)
Assorted sizes from 7mm to 25mm. Self-adhesive backs are worth the small upcharge - saves the glue bottleneck. Oriental Trading, Darice, Hygloss all sell in 500-5,000 count bulk.
Pom-poms (acrylic, assorted)
Mixed colors, mixed sizes (half-inch through 2-inch). Acrylic fiber is the norm. Hobby Lobby, Amazon, and craft-ed suppliers all sell in classroom-size bags.
Pipe cleaners (chenille stems)
The structural workhorse of the craft closet. Buy 12-inch stems in assorted colors. 500 stems last a year of weekly rotations for a typical elementary class.
Feathers
Craft feathers, dyed assorted colors. Cheap, light, effective. Useful for any "decorate your robot" or "make a creature" project.
Stickers (bulk)
Themed sticker books from Oriental Trading or S&S Worldwide are the cheapest-per-sticker option. Stars, smileys, shapes, animals, letters - all available in 500-5,000 count rolls.
Foam shapes and sheets
Die-cut foam shapes plus 9"x12" foam sheets in assorted colors. Adhesive-backed foam is a small upcharge but a large time-saver during class.
Sequins, rhinestones, gemstones
Adhesive-backed rhinestones are the best classroom version - no glue bottleneck. Standard sequins are fine if you already have a glue bottle rotation working.
Sorting + Counting Materials
Mostly free if you ask the community, but here's what to buy if you need them this week.
These are the kindergarten math manipulatives that cost almost nothing. A take-home note in every backpack fills three bins of sorting material in a week - ask for: dried beans, pasta, old buttons, bottle caps, coins (play or old foreign currency), small seashells.
Sorting trays
Plastic trays with 4-6 compartments each. 8-10 trays let a small group sort together. Hobby Lobby, Amazon, Learning Resources all sell these. An ice cube tray works in a pinch.
Counting bears (or counters)
Plastic bear counters in assorted colors, classic Learning Resources SKU. Useful for color sorting, counting-by-tens, and early addition. Generic counters work too; the bears just have staying power with younger kids.
Paper + Fabric
Bulk paper and fabric costs more than craft basics but pays for itself over a year.
Construction paper (bulk)
9"x12" assorted-color construction paper, 500-1,000 sheets. Lasts about a semester. Discount School Supply and S&S Worldwide are the cheapest-per-sheet bulk sources.
Cardstock (white + assorted colors)
Heavier than construction paper, needed for projects that stand up on their own. One ream of white plus one of assorted colors covers most needs.
Tissue paper
Dense assortment of colors. Works for collage, flowers, and light-diffusion projects with Makey Makey or micro:bit LEDs.
Felt sheets
9"x12" felt in assorted colors. Non-fray, easy-cut, works with glue or stitching. The bedrock of any felt-board or soft-craft project.
Yarn (bulk assorted)
Skip the single-color skein from the craft store. Get a multi-color assortment pack in 50-100 foot skeins - that is what kids actually want to grab.
Fabric scraps
Put a request in the Friday newsletter. One seasoned quilter will deliver a trash bag of scraps that lasts the year. Back up with a Goodwill run for old bedsheets.
Storage Solutions
A craft closet without a storage system becomes a rolling pile of glitter on the floor in three weeks.
The single most important line item after the consumables themselves is the storage. Labeled containers, a consistent return system, a closet with a door that closes. Without this, you will re-buy every item twice a year because half the closet walks off and the rest migrates.
Clear stackable bins (small to medium)
Sterilite, Iris, or generic clear bins 6-quart and under. Clear so kids can see the contents without opening. Sized so one supply type fits per bin. Stack on an open shelf.
A label maker
Brother P-Touch or Dymo LabelManager. Every bin gets a label. When kids borrow a supply and return it, the label tells them where it goes. Teachers who skip this step end up with the chaos bin.
Rolling drawer cart (10-drawer plastic)
The IRIS / Sterilite 10-drawer rolling carts hold a full craft closet's worth of small supplies in labeled drawers. Moves room-to-room. Fits under a counter. Cheaper and more flexible than a built-in cabinet.
Gratnells tray storage (for the bigger budget)
The gold standard for classroom storage. Modular trays, labeled slots, school-grade durability. If the STEM Studio has a dedicated room, a Gratnells unit is worth the money. If not, the rolling drawer cart gets you 80% of the way there for 10% of the cost.
What to skip
The common craft-closet mistakes that eat budget and class time.
Pre-packaged "craft kit" themes at 10x the bulk-supply price
"Ocean animal craft kit, 24 pieces, $36" is roughly $1.50 per kid for a pre-cut, instructions-included, nothing-to-think-about project. Bought in bulk from Oriental Trading, the same supplies come to ~$0.15 per kid. The pre-packaged version is fine for a substitute-teacher emergency plan, but building a STEM Studio around pre-packaged themed kits means the kids are decorating a foam shark outline, not designing their own creature. Bulk supplies plus a loose prompt beats a themed kit 10 times out of 10 in our experience.
Agree to Disagree ›Glitter glue sticks (glue guns clog)
Glitter glue sticks are sold for low-temp glue guns - you load a sparkly stick, you get sparkle in the bead. They clog the nozzle within a few uses, and the clog is painful to clear. Fine as a demo-once novelty, bad as a classroom standard. Use regular low-temp sticks for gluing, sprinkle loose glitter on top of the wet glue. Same visual result, no clog.
Agree to Disagree ›Scented markers in bulk
Mr. Sketch-style scented markers are immensely popular with 2nd-graders and reliably start fights over who gets the "best" smell. More than once we have watched a marker-based rotation turn into a 10-minute distraction because the grape marker walked off. For art-cart use they're fine; for a STEM Studio rotation where markers are one of six stations, regular classroom markers cause less drama. Not a safety issue - a classroom-management one.
Agree to Disagree ›Single-color / single-variety mega packs
A 5,000-count pack of all-red pom-poms looks like a great deal until you realize kids wanted green, blue, and purple too. Always go assorted on the first order of any craft basic. Specialty mega-packs of a single color only make sense after you know the room's specific needs (e.g., a school-color-themed project).
Expensive "classroom art kits" with curriculum attached
Some vendors sell "art-integrated STEM kits" at $80-$150 per unit. They bundle commodity craft supplies with a paid curriculum booklet. The supplies are overvalued (maybe $15 of materials) and the curriculum is replaceable with any free lesson plan from the internet. Skip.
