Merlyn, can you expalin your method a bit more, it sounds good but I'm not sure exactly what you're doing... Also which way round are the PJ's, foot plates poking your back or the other way?
Does anyone know where you can get straps like on the knee bars. I think they're great and want to use them to back a shoulder sling for them. If they had that clip thing like on the knee bars too that'd be awesome. Have little loops one the end too. So two straps, both with loops, one with clip thing on. One loops round knee bars and through it's own loop end thun goes down over your shoulder, over end loops round the feet and clips on to the upper strap. The straps'd have to be longer than they are on the knee bars though, at least half a meter each should be good.
