After a lot of thinking and a couple of trials, decided that pieces of base plate would work better than a whole base plate. A pair of kitchen scissors did the trick.

Pieces had to be three by seven studs to fit the velcro fastener.

These four 16 x 16 plates connected by various other plates make up the base for the first part of the scene I’m intending to display outside my unit door.

Of the three bits of green base plate at the top, only the outside two have the wall mounts. The middle one is me testing its joining capabilities. Two wall mounts together will hold 4.5 kilograms the packet tells me. Plenty for the purpose.

What I discovered a minute after I glued the velcro fasteners to the wall … the two fasteners—one gripping the other and the thickness of a bit of base plate—are nearer to two plates thick than one.

Meaning I’ll probably need to add a two by one plate to the back of all the joiner plates, for the scene to hang straight against the wall. That’s my next thing to do.

He’s got the boat stuck on a sandbank, right?
