Most items are made to order and start life as one of the rolls of material in my workshop. So, if you want a'tweak' to your personal taste, all you have to do most of the time is ask. If you want it in a different colour or even a different material, that's just a question of getting a different roll of material off the rack when I make it.
Please understand though that if you want significant changes this may affect the price of the item - I will always supply a quotation if the price is affected.
