No Dormouse, unfortunately I didn't get any pictures of the quilt. I remember seeing it near the admissions counter but as we were with the kids, they were halfway through the door to the conservatory before I was done paying.
As for your second question, the girls are aged 3 and 6 and they both loved the butterflies. I think this place would be interesting for any age group from toddlers on up. Who wouldn't love having butterflies flying all around you. The 3 year old was a little intimidated at first til one of them landed on her and she realized the butterflies are really pretty...and they don't bite!
