You’re standing in the middle of a Michaels, surrounded by the scent of cinnamon brooms and the hum of fluorescent lights. You need foam board. Not just any board, but the kind that won't warp the second a drop of glue touches it.
Honestly, most people walk in, grab the first white sheet they see, and head for the checkout. Big mistake.
Foam board Michaels crafts selection is deeper than you think. It's not just "white poster board with a middle." It's a whole ecosystem of densities, thicknesses, and—if you’re lucky—specialty finishes that can make or break a 3 a.m. school project or a professional gallery mount.
The Reality of Picking the Right Sheet
I've seen it a thousand times. A student buys the standard 3/16-inch board for a heavy diorama, and by morning, the whole thing is bowing like a soggy taco.
If you're doing something structural, you've got to look at the 1/2-inch thick options. Michaels usually stocks these in the 20" x 30" size. They’re beasts. They are surprisingly lightweight but offer that rigid backbone you need for architectural models or heavy-duty retail displays.
Then there’s the Elmer’s brand vs. the store brand. Usually, people think they’re paying for a name. Kinda. But Elmer’s tends to have a slightly more "tooth" to the paper surface, which helps when you're using markers or specific adhesives.

The Creatology line is the bread and butter for kids' projects. It’s cheaper. It’s colorful. But if you’re trying to do fine-scale terrain building for D&D or a model train set, the paper on the cheaper stuff can be a nightmare to peel off without gouging the foam underneath.
Why Thickness Actually Matters
Let’s talk numbers, but keep it simple.
- 1/8-inch: Great for "Poorhammer" (budget Warhammer terrain) or mounting photos in a thin frame.
- 3/16-inch: The "standard." If you don't specify, this is what you're getting. Perfect for science fairs.
- 1/2-inch: The heavy hitter. Use this for standing floor displays or when you're building furniture for a dollhouse that needs to actually hold weight.
Colors and Finishes You Didn’t Know Existed
White is boring. We know this.
Michaels usually has a stash of black foam board, which is a godsend for photographers. It absorbs light instead of reflecting it. Pro tip: if you’re making a "memory board" with photos, black foam board makes the colors pop way more than white ever could.
And then there's the cork-faced foam board. This is a weird hybrid. It’s basically a thin layer of cork laminated onto a foam core. It’s way lighter than a solid corkboard and a lot cheaper. You can find these in 24" x 36" sizes. Just be warned: some users have found the cork layer can be a bit thin, so don't expect to pin a heavy winter coat to it.

Specialty Variations at Michaels:
- Dry Erase Foam Board: Yes, it’s a thing. Great for temporary scoreboards or "to-do" lists in a dorm room.
- Bi-Fold and Tri-Fold: These are the classic "I forgot my project is due tomorrow" boards. They stand up on their own.
- Adhesive-Backed: These have a "peel and stick" surface. They are incredible for mounting posters without getting those annoying bubbles you get from spray adhesive.
The Secret to Not Ruining Your Project
You’ve got your board. Now, how do you cut it?
Most people use a dull box cutter and wonder why the edges look like a beaver chewed on them. The foam inside (polystyrene) is finicky. If your blade isn't "shave-your-arm" sharp, it will snag and tear the foam instead of slicing it.
I always suggest the Logan FoamWerks tools if you can find them in the aisles. They have specific cutters for straight edges and even bevels. If you’re just using a utility knife, change the blade every three or four long cuts. Seriously. Blades are cheap; a ruined $9 board is annoying.
Adhesives: The Good, The Bad, and The Melty
Here is a fun fact: certain glues will literally melt the foam core.
If you use a high-heat hot glue gun and the glue touches the exposed foam on the edge, it will dissolve it. Use a low-temp glue gun or specific foam-safe adhesives. PVA glue (like basic white school glue) works fine, but it takes forever to dry and can warp the paper if you use too much.

Double-sided tape or scrapbook adhesives are actually the "secret weapon" for foam board. They provide an instant bond and zero moisture, so your board stays flat as a pancake.
Practical Next Steps for Your Next Michaels Run
Don't just drive to the store and hope for the best.
Check the Michaels app first. They almost always have a "20% off All Regular Price Purchases" or a "40% off One Item" coupon. Since foam board can get pricey—especially the multi-packs or the 1/2-inch thick versions—that coupon is the difference between a $15 trip and a $9 one.
Also, look for the "Buy in Bulk" (Michaels Pro) options if you’re doing a whole classroom or a wedding. You can get 10-packs of the 20" x 30" sheets for a much lower per-unit price.
Before you leave the store, check the corners. The biggest tragedy in the craft world is getting home and realizing the bottom corner of your board is "dented." Foam board is fragile. Look for sheets that haven't been slammed into the floor by a distracted shopper. If you’re buying the large 32" x 40" sheets, ask the cashier for a large bag or some scrap cardboard to protect the edges during the car ride home.
Start by measuring your project space and deciding if you need the structural integrity of a 1/2-inch board or the versatility of a standard 3/16-inch sheet. Grab a fresh pack of blades while you're in the tool aisle—your edges will thank you.
