Hi! I previously made two of these sofas into a sectional (amazing, easy, everyone loves them) and I'm planning on adding a third this weekend to make a u shape sectional.  My question is: Do you have a cut list for the 11 2x4's?  I used more than 11 each time. and I also had alot of waste...

Cut your 9 2x4x10 at 72” first, then use scraps for 25 1/2

use the 10th 2x4x10 to cut the 4 other 25 1/2

the last 2x4 could be only 6” as you will cut your 2 last at 28 1/2

That’s 10 - 2x4x10 and 1 - 2x4x6 with 11 scraps (9x 22.5 - 1x19 - 1x15)

it is plenty!

Your cut list is deceiving. If I’m building to suit specific cushions I don’t need 13 pieces that length. 4 of them still need to be the length of the height of the arms. Kind of a pain in the ass when you’ve pre stained/sealed based on the cut list and then end up with pieces that won’t work.
