sounds expensive... inc postage £24.34 for a few rabbit skins, especially if you've never done it before?
'If you've used the tanning kit you will already know that it's not just alum', actually couldn't get a straight answer from your company when I asked what was in the kits, just 'chemicals you find in domestic water supply' so it could be salt and alum.
Got good results from the kit but also had no trouble getting the same first time with alum, and the nice white colour on flesh side, like suede.
