Natural vegetable tanned calf approx. 1.0mm sold either as a 4 square foot piece, approximate measurements will be 60cmx60cm (24"x24") or as a whole piece. Occasionally when cutting 4sf, it could be 30cmx122cm (12"x48") however this is not the rule and it is best to contact the Store if you definitely require a piece of this size. At this weight, the leather is very good for small leathergoods, wallets, card holders, linings, gussets, scabbard holders, jewellery making, sculpting and miniature work. The leather can be dyed and stained and carved/tooled and embossed.
