If you love those wonderful pictures of puzzles, want to try your hand at it but hesitate because of time and necessary space, this is just the thing for you.
You'll never have to hurry to finish a puzzle again, you can spend only as much time as you want to, then just roll the half done puzzle to this absolutely wonderful invention. Every puzzle maker must have one.
As long as you do the rolling very carefully and slowly, you'll be sure your puzzle is safe in it. After being rolled, it fits into almost anywhere, I keep mine behind my desk, you could put it into a cupboard or under your bed, no problem. When you want to continue, all you have to do is to unroll it, and start where you left. No more dust collecting puzzle pieces, no more worries about other people accidentally ruining your precious work.
The downsides are, the elastic bindings may go loose in time, and after making 10 puzzles the hold of the fabric on pieces get weaker. This may result in some pieces getting misplaced while unrolling, but it's avoidable with slow movement and caution.
