Hi, Can someone point me in the right direction with regards to my seat build? 
Most likely I have bitten off too much for my first  attempt at solo seats but hey ho!  I have two seat pans which I have foamed up ready to start thinking about putting leather to and have a few questions. 
1, Lace what size? I have looked at our local web sites in the UK and have a choice of 1/8", I notice in the tutorial 1/4" used 
2, as the top will have to be cased to obtain the correct shape should I do that before carving? or carve then shape? 
3, what is the measurement of overhang used for the lacing holes 
Attached a photo of seat base, any help advice would be appreciated
