How to set a crack climb

It can't be done, not very well anyway, in an indoor climbing gym. When I went this afternoon to set, all I could picture were the lovely routes I'd done in J-Tree. So I set the route I could with the holds I had. Just another one of my little sweet ones, nothing contrived or hard. Did a spot of traversing and bouldering, and went home.
Trashed out for a bit watching "Lost" on beloved spouse's laptop.
