Circular Cardboard Bookshelf
This design is based on a apostrophe. After a few requests for a tutorial on this curvy cardboard bookshelf (inspired by Patricia Dessoulles), I decided to have a go at it.
I covered it with pearlescent wrapping paper and it took just two days to complete from drawing to finish.

Sketch Design
The cupboard appeared like a 'comma' shape so I needed to trace a perfect circle as part of the template.
After deciding on the design, I traced it out on baking paper, drew the rest of the shape freehand, fitting into the small piece of cardboard I had found and cut it out.
This design is suitable for smaller pieces of cardboard. The two halves can then be put together if you cannot find a larger piece of cardboard.
I cut out the centre for an uneven shelf level to add a bit of dynamic to the final appearance.
Cut three frames for shelf support and one silhouette backing. Only cut struts for two inside frames. They are cut half-way.

Trace and Cut Silhouette & Struts
The struts are the supports for each level on the shelf. Its important when cutting struts to check if the direction of the grain is vertical. If the grain of the strut horizontal the shelf will bend.
The height of the strut will be equal to the height of each shelf level.
The struts are cut half way between the inner supports and the strut. The part I enjoy most is fitting the struts in each layer like a 3d jigsaw puzzle.

Join the Pieces
Check that each frame you've cut is identical to the layer in front of it. I found that the whole shape is thrown out of whack by irregularities in shapes.
I used a bit of quick sticking, polyurethane craft glue to join the struts at the front layer and back layer and edges. This seemed to work faster than using the electric glue gun. While I worked out side in the sun, everything dried pretty quickly.
Now wet the watercolour paper tape on the sticky side, trim slits for curves, press edges firmly together and paste on tape to strengthen your inner struts.

Decorate
Heat a pot of cornflour, water and pva glue to make a thin paste.
I brushed this glue mix onto the cardboard bookshelf when it had cooled. After putting out in the sun, it dried rock hard.
Working out the general amount of wrapping paper to use
First I placed the wrapping paper over a section here and there. I pressed the sides to form a crease all around each shelf layer. Then I trimmed around this pressed template with a 2.5cm border all around.

Also Camille has a detailed site about cardboard furniture design for beginners and is a great introduction into the cardboard design world. Especially helpful are ways for a more professional finish.

Waterproofing - Another Way to Finish
I recently found the secret to creating a flat finish to your cardboard furniture.
The cardboard tended to sink once I'd painted it with the rice flour glue paste and the paper crumbled.
I did a bit of search and found Veronica's detailed site (in French) about how to give a professional flat finish to the surface of your cardboard designs.
I used the DIY joint compound recipe - the ingredients include calcium carbonate (cement mix), water, pva wood glue, preservative (such as vinegar / tea tree oil.)
Add (1:2) 1 part water to 2 parts calcium carbonate cement powder. Stir in 1 Tbl pva wood glue.
Store unused joint compound in a sealed container and it will remain workable indefinitely.
I painted this mixture onto the cupboard, dried it then repainted the top surface with the DIY joint compound mix. It dried to a hard, rocky surface.
If I was more careful, I'd paste it on with a spatula then filed it down smooth, and used wet n'dry sandpaper till it was flat.
However, in the picture below, I kept all the lumps and bumps and think it adds a bit of character to the final cupboard. Next time though, I might blend it thoroughly for a flat, chalkboard look.
