Hi and welcome to Perfectly Reasonable Necessities. Here's where the whole range of products I currently have is available for purchase.
The size of timber, for relief carvings and signs, has a maximum size of 750mmx750mm and 50mm thick. The supply of material can either be sourced by myself or you can supply it for me so you get the exact material you like as timber tastes can be very sbjective. For CNC the file type I use is STL and that can be emailed. Each job or product will vary in time frame depending on complexity, detail, and finish. The base timeline for custom works will be 3 weeks so I can produce the best product I can.
