I have a legal size sheet printed up of a drawing of a cue. It has a place to record all of the parameters or options on the cue. Everything from joint material and length to what type of butt cap and length and all in between. I also have a binder with pictures of about 1,000, full size inlays that a customer can browse through. Each image has a number so that number and type of material to be used is recorded on the schematic in it's proper place. Once the design is finished and recorded I print a copy for the customer. In this manner there is no room for arguments later as to details as all is on the sheet including purchase price and completion date.
