The next level strats right here.
I rip my traced out sections down to individual parts with a seam allowance for trimming. It's a bit more wasteful on foam but it lets you have more than enough surface to place your steel ruler on or to cut appropriate bevels.
Having individual parts lets you better manipulate them on the table and keep track of all your pieces for prep and assembly. You might have seen my pattern stacking knolling technique on Bucket to Boots, it may look like chaos but it helps for speed building.
