Step 1: Materials
ikea frame ($2.00/pair I think)
something to be a dry erase surface: dry erase self-adhesive sheets (shown), glossy white plasticky shrinky dink sheets, transparency sheets, glass, something like that (price varies)
cardboard or thin wood for extra backing
hammer and 1 cm hole punch
bubble wrap spacing template (attached pdf)
Update: use a cricut
Step 2: Trim Acrylic Sheet
This will allow you to expose a strip of bubble wrap alongside the whiteboard material.
Step 3: Optional: Cover the Acrylic Sheet With a Dry Erase Surface Material
I went even further and punched out a line of 1 cm holes for the bubbles to line up into. That was quite difficult and took a few tries. I even went so far as to create a perfectly aligned template using Sketchup (see attached pdf on the materials page), which helped with the alignment a great deal. Update: this can be done much more easily with a cricut and the svg file provided on the materials page
Tape the dry erase material down on top of a magazine. Tape the template down over that. Line up the punch over the holes. Rap with the hammer two or three times to create a hole. Carry on like that for 14 holes in this case.
Step 4: Cut Additional Backing Board for Support
Using the paper insert of the Nyttja frame as a template, cut out a similarly sized rectangle from thin plywood - approximately 3mm thick. This will provide extra backing which makes it a little easier to snap the bubble wrap.
Step 5: Assemble
Align it in the frame alongside the whiteboard surface.
Lay in the backing board and close up the frame.
Step 6: Epilogue
A silly idea has been brought to life.
Cons: Getting the bubble wrap strip to line up properly is a bit finicky. Creating the template was helpful, and would be an even easier job for a laser cutter, if I had one... (hint hint)
Snapping the bubble doesn't always work. Sometimes they just deflate silently, which is disappointing.
This would be much better if it were manufactured in some proper way by whoever makes shipping materials.
Thank you and good night.
