Thanks everybody for your suggestions, sorry I haven't got back before this, but I've spent the best part of 3 days in bed with a cold bug that has been going around.
I managed to get to my LQS yesterday - a 90 minute drive away - and found out where I can get the liquid and fabric I need. I thought they may have kept it; they don't but have given me the website for where they get what they use from. Have to get it from interstate, so that will have to wait until after Easter.
Thanks again for your help.
