eebee's Adventures Playmat and Activity Playhouse

This product is NOT cheap, but the quality is excellent. I bought this specifically for my 6 month old to play on safely and not be concerned about the foam mats and toxicity. This is a GREAT mat, but the problem is as she got older and more interactive, I tried to set it up as a playhouse as the pictures depicted, however the velcro tabs are not placed properly or are supportive enough to hold the playhouse together so an average toddler won't tear it down easily. If someone has better instructions the manufacturer didn't provide, I'd appreciate the help. Thanks!
