On this photo is something I have been working on last week: A kid's seat!
I used 3 removalists cardboard boxes and some PVA glue.
This is the raw product. I'll show you the painted product at the end of the week!

This one is a wall shelf in cardboard I made for one of my sons. The design was chosen to match the standing shelf he already had for his books.
I used double wall cardboard boxes with the "Bleuzen technics" to create the shape that I sealed with PVA and painted with acrylic paint and water based varnish. All his small nic nacs can now be kept away from his little brother's hands and mouth.
