I trust you to do the seam allowances as you see fit. He ended that video talking about how we get to make it our own at the end anyway so if anyone wants to slice and dice, they will. Reach for your joy as you build our quilts! That joy will scream out at us when we finally get our flimsy back.
If there was something we did not want, it should have been our our preference list. :-) It is on us if we didn't list it, not you.
May I double dare you to try to do something I am not going to like on my flimsy??
