Beistle
Building Block Party Cutouts
from $7.00
Classroom bulletin boards and playroom walls are where these building block cutouts earn their keep: 20 multicolor pieces per package, from 4 to 11.25 inches, printed on both sides so they work in windows where both faces show. The size mix is the useful part; small pieces fill gaps between big ones and the display looks planned instead of scattered.Sold by the package (20 cutouts) or by the case (240 cutouts).
Beistle
Building Blocks Party Tablecover
from $7.00
Fifty-four by 108 inches of plastic covers a standard banquet table with overhang to spare, and the multicolor building blocks print does the decorating for you. Frosting, juice, and marker mishaps stay on the cover instead of the table, and cleanup at the end is one roll-and-toss.
Material: plastic
Sold by the package (1 tablecover) or by the case (12 tablecovers)
Beistle
Building Blocks Party Streamer
from $5.78
Six colorful pennants on a single string make this building block streamer an easy pick for a kids' party wall or the space above a doorway. It's printed on one side, so hang it flat against a surface rather than across open space where the back shows.
Color: multicolor
Size: 9" x 6'
Sold by the package (1 streamer) or by the case (12 streamers)
Beistle
Building Blocks Party Backdrop
from $22.50
Thirty feet long and four feet tall, this plastic backdrop covers an entire wall in a multicolor building blocks print, so the room reads as decorated the moment anyone walks in. Tape it up, take the photos, then peel it down and save it; the lightweight, durable plastic is reusable for the next party.
Adheres to walls with tape
Sold by the package (1 backdrop) or by the case (6 backdrops)
Beistle
Building Blocks Party Photo Prop
from $9.80
Kids' birthday photo walls need one big anchor piece, and this multicolor building block prop, 37 inches by 25 inches, is sized for a door or a stretch of blank wall. Stand the birthday kid in front of it and every phone at the party comes out; it reads clearly from normal photo distance, which is the entire job. Graduations get the same mileage out of it.Sold by the package (1 prop) or by the case (6 props).
Beistle
Building Block Party Whirls
from $7.70

"In Love with Beistle products! I recently purchased Beistle die-cut products from Bulk Party Supply, and I'm beyond impressed! The shipping was incredibly fast, and the communication throughout the process was top-notch. The quality of the die-cuts is outstanding—the pumpkins were amazing, the cupids looked terrific, and the hearts were perfect. The packaging ensured everything arrived in pristine condition. Plus, the prices are a great deal! I'll definitely continue doing business with both Bulk Party Supply and Beistle Co."
