I drew some sketches, but I can't find them. That's always the first step. Now, instead of making a mock-up out of cardboard, you can skip right to building if you model your idea precisely in a 3d modeling program. I use Rhino 3d, which is fairly user friendly but it ain't free. You can Try Google sketch-up. Free and pretty easy to pick up.
Before I explain the build, I'll list the basic materials here.
1. Sheet styrere 0.40" thickness 2. Blue styrofoam 1" thickness 3. 1 - 8' length of foam crown molding - profile is your choice 4. 2 - 8' length vinyl moulding - for top and bottom of dresser 5. Double Side Tape - I used Elmer brand any type should do - wider is better 6. 1 - 8' length of plastic drywall corner bead 7. PL Premium - check the picture - most people buy it in a tube for use in a caulking gun - the kind I used is a little different 8. Utility knife for cutting plastic and foam - table saw works great if you have one 9. Latex caulking - optional - I used it to fill the joints where the body of the dresser meets the top and bottom 10. White Latex Paint - helps make the dresser look like wood - a lot of people were fooled 11. Ceramic Knobs - not pictured here- they're all on the dresser 12. 1 chucky mask - make it yourself or try Handiboy.com 13. 1 pair of child's overalls, pajama pants, and a shirt 14. 1 pair of child's shoes 15. Cotton stuffing 16. Lots of toys, and some stickers from the dollar store 17. Whatever nuts and bolts you can find to attach them all to the dresser
Now, I kind of skipped ahead just a tiny bit here, because I neglected to charge my camera the first night I started my build. At this point the main box of the dresser is assembled. What you need to know is this:
1. The blue styrofoam was cut on a table saw. You can use an exacto knife if you don't have a saw, it will just take you a little longer. Please wear a mask though. The blue foam dust is not good to breathe.
2. The corners of the foam were routered on a router table, so that the plastic drywall corner bead would fit over the edges. The individual panels are held together with double side tape. The corners are held on the same way,
3. The fronts and sides of the dresser body are cover in sheet styrene, again using double sided tape. This stuff sticks good. The Plastic sheets come from any plastic supply store and a 4' x 8' sheet of .040" runs about $15
4. This picture also shows the base of the dresser which will be shown further in a later step.
