Introduction: How to Make a Cardboard Standup
I run a small library with a very limited budget, so I have to get creative when it comes to decorations. I decided to start making my own standups as a way to advertise various programs at the library.
For this project, you'll need...
- color printer
- a computer
- cutting mat
- rotary cutter or xacto knife
- foam core board or cardboard
- duct tape
- spray adhesive
- foam brush
Step 1: Find Your Image
You can take your own or find one online. The higher the resolution of the photo, the better it will look when enlarged. If the image has a background that you don’t like use a photo editing software to clean it up. I decided to use one of my cats.
Step 2: Figure Out the Desired Final Size for Your Project
Figure out what size you want your final project to be. This site does a fairly good job of converting pixels to inches and inches to pixels.
Step 3: Download SmillaEnlarger
Step 4: Enlarge Your Image
Drag and drop your image into SmillaEnlarger
Then set your output height. There are other options, but height generally gives the best results. The number is in pixels. Use the site from Step 2 to figure out how many pixels will give you the height you desire. You will need to check to see the dpi settings for your printer.
Pick a name for your enlarged photo and choose where you would like it to be saved.
Click Enlarge & Save to save the photo.
Step 5: Print Your Enlarged Image
Now we are ready to print our enlarged photo. There are several different businesses, both
online and brick and mortar, which have the ability to print large images on a large sheet of paper. We do not have that ability, so we will have to print our photos across multiple sheets of paper.
Open up your enlarged image in Microsoft Paint. Then go to File > Print > Page setup
On the Page Setup screen, set your margins all to 0. It will then default to the smallest number possible. Under Scaling – select Adjust to 100% normal size. It will then show you how many pages the picture will print across.
Hit OK and then print your picture.
Step 6: Trim the White Edges Off Your Paper
I forgot to take pictures during this process with my cat picture. These are from a previous Batman standup I made for our superhero themed summer reading program.
I used a quilting ruler and a rotary cutter to trim the pages, but any straight edge and blade should work. I highly recommend using a cutting mat to protect whatever surface you are cutting on.
Step 7: Attach Your Trimmed Pages to Your Backing
Now it’s time to mount the papers onto a board. I used foam core board. It’s easy to find and inexpensive. You can use cardboard, but it’s not as stiff and doesn’t work as well for larger projects.
I recommend laying out all the pieces of paper on the foam core first. That way you can plan how many pieces of foam core you need and see what type of layout will work the best.
If you need more than one piece of foam core board, attach the pieces together with duct tape before you start gluing the paper to them.
Start by spraying the foam core with a spray on adhesive. I’ve found that 3M Multipurpose Spray Adhesive works the best. Once you’ve sprayed the adhesive, start laying down the papers one row at a time. Most spray adhesives are tacky, so you have the ability to adjust the papers for a short amount of time.
Continue laying down the papers, reapplying the spray adhesive as needed, until all the pieces of the paper are glued down.
Step 8: Seal the Seams
Once all the papers are glued down, we need to seal the seams. Using a foam brush, cover all the seams with mod podge. I used the type that was just for paper and has a matte finish.
Step 9: Trim the Edges
Once the seams have dried, trim the edges of your project to whatever shape is desired.
Step 10: Attach a Stand to the Back of Your Character
The final part of this process is putting a stand on the character. If you just want something to attach to a wall or the end of a bookcase you can ignore this last step.
Cut a piece of cardboard or foam core board about ¾ the height of your standup character and about 4” wide.
On the bottom cut about a 5 degree angle. This will cause the standup to lean very slightly backwards. If you want it to lean more, cut a steeper angle.
Take self-adhesive Velcro and attach one strip to the middle of the cardboard stand up and the other strip to the edge of the stand piece. You want the Velcro to be even with the bottom of the standup.
Attach the stand piece to the back of your stand up.
