Thank You for your nice words, I appreciate it. I have only been doing this for a year, if I can do it so can you. Just don't do it better than me!
Okay, where to start? I normally use a 6/7 oz piece for the top, I like to be able to tool pretty deeply, and it saves the seat from wrinkling. For the sides I use a 3/4 oz, it’s easier to mold to the form of the seat and you don’t want to add too much thickness to the bottom.
When using the ‘x’ stitch I do a single row of lace holes on each piece 3/8†in. The top seat piece is laced over the side piece and when the stitching is pulled taut it locks the too pieces in place, very simple. Otherwise I use the Spanish round braid ( I believe) and butt the edges together, this being my favorite. It lays flatter, more comfortable to ride.
The foam I use is black closed cell neoprene. It comes in different depths ands lengths. I build it up in layers to get the seat thickness I need. I then use a rasp to shape it. It is water proof which is important, however I always tell my customers that this doesn’t mean the leather is.
Hope this helps.
