henry sleeps either on the corner of my bed, atop silk flowers or in my messenger bag. no really, i have pictures, i'll post them later. the bag i'm currently using has a silk flower on it. he went berzerk with glee last night. there's now cat spit all over the flower from him licking it.
leeloo sleeps somewhere in the studio (easier to type than workroom) under the furniture in a nest of empty plastic shopping bags, or right behind and under my computer chair.
jack sleeps in the rut in doc's matress, on doc's living room chair and on top of henry when possible. he really hasn't found his "thing", he's still young.
if i wanted them to sleep all together, i would simply make a quilt of rip-stop fabric. they would never leave it.
i continue to look for commonalities so i can make them a big bed they will all sleep in. but i think i'm going to have to go with the parachute fabric quilt.
