Someone posted a printable cutout of the Moomin House, so I resized it, and had a fun time putting it together.
I cut out the under-stairs door and placed the magic tophat in there.
If there are no objections, I can post the resized version here. Mods, just let me know if that's ok to do.
Edit: By request, please see the pages below. When you print them, make sure they're simplex and all to the same sizing percentage. I happen to have Letter size paper at home (216x270cm, 8.5x11in), so they're sized for that.
Done!
Thanks!
