playhouse frame. Links to apartment therapy, collapsible indoor playhouse. PVC frame much sturdier than flimsy tent frame, and would be rad if you sewed a matching tote bag-sized pocket (attached or unattached) the whole thing could be folded up into when not in use. Love self-contained playthings over here, especially bulkier items.
What a fabulous post! We have around 50 pounds of Legos, it is overwhelming. Now if I could get my kid to keep the legos organized in the various systems I've started for him, I'd be in great shape. lol
