The models for these pictures are my boys, age 7 and 10, who are not famous for their patience. Despite the numerous steps, it took them about 5 minutes to complete the project; it takes me about 45 seconds.
Step 1: Materials
The only tools you need to complete this project are:
A ball point pen
A pin or sewing needle
You will also need to download the PDF template and print it with a color printer. The image is the size of a 4 by 6 postcard, but you can scale it to any size you would like.
You can download a (free) PDF from my website. Please note that most of my PDF files are protected so that they cannot be copied or modified, so if you try opening them with image editing software, such as Illustrator, a password will be requested. Use Preview, or Adobe Acrobat or other PDF viewing software instead, and you will be able to open and print the file without entering a password.
Note: the photographs in this instructable show a pre-printed postcard I made, not the PDF file printed on a sheet of paper -- however the instructions are the same.
Step 2: Scoring Technique
A ball point pen is the perfect tool for this job -- when pressed down firmly it will dent the paper without damaging it -- but its drawback is that it will (usually) do what it's supposed to do. Draw a line. Since you don't want to mark your picture, you will need to score the card on the back side of your paper.
Always use a ruler when you score, so your line will be perfectly straight.
If you prefer to see the picture as you score, you can try using a knitting needle, a stylus pen, or even a bone scoring tool they sell in art supply stores. You want something sharp enough to draw a line, but not too sharp or it might damage the paper. I use a ball point pen which I spent hours emptying of its ink. I only recommend this option if you are planning to make many, many pop-ups. Washing the ink away was messy, long, and extremely tedious.
Step 3: First Fold
Fold your sheet of paper along the score line with the image facing out.
Step 4: Cut the Table and Chair
Step 5: Score the Table and Chair
Step 6: Push the Table Forward
Step 7: Cut the Pop-up Doll House
Step 8: Score the Doll House
Step 9: Make the Chair Pop Out
Step 10: Make the Table Pop Out
Step 11: Make the Doll House Pop Out
Pinch the edge of the table as you slowly push the doll house forward. As you continue to fold, make sure the edge doesn't rip by pressing down with your fingers on both sides of the card.
Once the card is folded properly and the edges have been creased it is no longer at risk of ripping (under normal, fairly gentle play conditions).
