Monsters University Theme Costume Ideas for All Ages

DIY Monsters University Theme Crafts and DecorationsThrowing a Monsters University–themed party or decorating a kids’ room is a fantastic way to combine playful color, quirky characters, and collegiate spirit. This guide covers DIY crafts and decorations that are budget-friendly, easy to make, and richly themed — from invitations and banners to centerpieces, photo backdrops, and party favors. Most projects use common craft supplies and can be adapted for different ages or party sizes.


Color palette & style guide

Stick to the film’s energetic, slightly retro-collegiate look:

  • Primary colors: royal blue, lime green, purple, orange
  • Accents: white, black, polka dots, stripes, and textured felt or fuzzy fabrics
  • Fonts & graphics: collegiate block lettering, varsity numbers, and simple silhouettes of Mike Wazowski (one big eye) and Sulley (furry, horned shape)

Supplies you’ll commonly need

  • Cardstock in assorted colors
  • Construction paper and patterned scrapbook paper
  • Felt sheets (blue, green, purple) and faux fur (if available)
  • Acrylic paints, paint pens, and fabric markers
  • Scissors, craft knife, cutting mat, and ruler
  • Hot glue gun and craft glue
  • String, twine, and ribbon
  • Foam balls (various sizes) and wooden dowels or skewers
  • Googly eyes (large and small)
  • Printable templates (characters, logos, pennants) — create or trace simple shapes

Invitations: “You’re Accepted to Monsters U!”

Make invitations look like acceptance letters or student ID cards.

  • Option A — Acceptance Letter: Use cream cardstock, print or hand-letter “Monsters University” at the top, include playful copy like “Congratulations — You’re Accepted!” Add a faux seal using a circle of red paper and a stamped “MU.”
  • Option B — Student ID Card: Cut cardstock to 3.5 x 2 in, add a tiny photo or illustrated Mike/Sulley, include name, “Major” (e.g., Scaring 101), and a student number. Laminate with clear contact paper for durability.

Entrance decor & banner

  • Giant pennant banner: Cut large triangles from cardstock or felt, alternate colors and patterns. Stencil or paint letters to spell “MONSTERS UNIVERSITY” or “WELCOME RECRUITS.” String with twine and hang at the entrance.
  • Door wreath: Use a foam wreath base wrapped in faux fur (blue or purple) and attach felt horns, googly eyes, and small pennants.

Photo backdrop: Monster Dorm Hallway

Create a colorful backdrop for photos that looks like a Monsters U dorm corridor.

  • Base: Large roll of kraft or butcher paper painted royal blue or green.
  • Locker row: Cut long rectangles from cardboard, paint alternate colors, and add paper handles or number decals. Stack and glue to the base to suggest hallway lockers.
  • Props: Giant foam cutouts of Mike’s eye, Sulley’s silhouette, and pennants. Add a bench (painted cardboard) and cap-and-gown props for guests to wear.

Table centerpieces

  • Plush mascot clusters: Arrange small plush versions of Mike and Sulley (or DIY felt versions) with mini pennants, faux books, and tiny chalkboard signs indicating table numbers.
  • Scare-lab jars: Fill mason jars with colored water (food coloring) and plastic “lab” labels. Add glow sticks before the party for an eerie glow.
  • Fuzzy pom-pom monsters: Make pom-poms from yarn in theme colors, glue on googly eyes and felt horns, and mount on dowels placed in painted flowerpots.

Balloons & ceiling decor

  • Polka-dot and stripe balloons in palette colors.
  • Eye balloons: Draw or stick a single large eye on lime green balloons to mimic Mike. Use permanent marker or pre-cut vinyl circles.
  • Hanging “fur” streamers: Cut strips of crepe paper or fringe streamer in blue/purple, twist and hang from the ceiling to evoke Sulley’s fur.

DIY character crafts (kid activity stations)

Set up a crafting table with templates and materials so guests can make their own Monsters U keepsakes.

  1. Felt Monster Masks
  • Pre-cut mask bases from sturdy cardstock. Provide felt pieces for horns, eyebrows, and ears. Glue and attach elastic for wearing.
  1. Build-a-Monster Plushie (no-sew)
  • Provide felt shapes, stuffing, safety googly eyes, and fabric glue. Kids assemble simple flat plushies by layering shapes and gluing the edges, then stuffing lightly.
  1. Monster Eye Suncatchers
  • Using clear contact paper, layer tissue paper scraps in a circle and top with a cutout pupil. Seal with another sheet and trim into an eye shape; hang in windows.
  1. DIY Monster Pennant
  • Small felt pennants kids decorate with letters, pom-poms, and fringe to hang on necklaces or backpacks.

Food & dessert decor ideas

  • Cake: A two-tier cake — bottom tier textured like Sulley’s fur (use fur-effect piping or coconut dyed blue), top tier a smooth lime-green Mike cake with one large fondant eye.
  • Cupcakes: Colorful frosting with mini fondant horns or eye toppers. Use cupcake wrappers in varsity stripes or polka dots.
  • Snack labels: Make little “Scare Snacks” cards using varsity fonts; label popcorn as “Ghoul Corn,” blue jello as “Scream Gel,” etc.

Party favors & goodie bags

  • “Freshman Kit” bags: Fill small drawstring bags with themed items — sticker sheets, eye-shaped sunglasses, mini notebooks, and a certificate of acceptance.
  • Custom water bottles: Use printable labels: “Monsters U — Hydration Lab” and wrap around inexpensive bottles.
  • Mini diploma scrolls: Roll paper with a congratulatory note, tie with ribbon, and add a small MU sticker.

DIY signage & props

  • Varsity pennants and directional signs: Make signs pointing to “Scaring 101,” “Dorms,” and “Cafeteria” using painted plywood or thick cardboard. Distress edges for a vintage college look.
  • Photo props on sticks: Create mortarboards, glasses, horns, and foam megaphones to hold in photos.

Lighting & atmosphere

  • Colored uplights or LED strips in blue/green/purple create an immersive glow.
  • Use battery-operated string lights inside jars or behind backdrop cutouts for soft ambient lighting.
  • For a scare-lab vibe, play the Monsters University soundtrack or a playlist of upbeat, quirky tunes.

Safety & accessibility tips

  • Avoid small detachable parts in crafts for toddlers; supervise glue/gun use.
  • Provide non-toxic glues and child-safe scissors at kids’ stations.
  • Offer a low-sensory corner (fewer lights/sounds) for children who may become overstimulated.

Timeline & planning checklist (1–2 weeks before)

  • 10–14 days: Finalize guest list, order any custom items (plush, banners), and download/print templates.
  • 7 days: Start making durable decorations (backdrop, centerpieces).
  • 2–3 days: Assemble invitations, favor bags, and finish craft station prep.
  • Day of: Set up backdrop and tables, test lighting, lay out food and activities, and add final touches (balloons, props).

Printable templates & patterns

Create simple printables for:

  • Mike and Sulley silhouettes
  • Pennant letters and numbers
  • Student ID card template
  • Eye suncatcher circles
  • Locker front pattern for backdrop

(If you want, I can generate printable SVGs/PDFs for these templates.)


These DIY projects let you scale effort from casual decorations to a full immersive experience. Use a few key signature pieces (big backdrop, character centerpieces, themed food) and supplement with smaller crafts and details to get a polished Monsters University atmosphere without breaking the bank.
