bearing in mind that if you need samples then they have to be individually cut, sewn, inspected, packed and sent in the post (Royal Mail)
Bamboo cloth is not widely available so we no longer make bed sheeting and pillowcases , our terry towelling is 90% viscose from Bamboo, 10% polyester for strength, 400gr/m width 150cm but it contracts by over 10% in cutting so base your calculations on 135cm wide cloth x any length. don't forget hems take up 3cms
