Hum... I didn't press it till I was through! ( It's wrinkled now. I'll have ta press it again!)The hardest for me was pressing that fitted black sheet to cut the black strips. I've got an AccuQuilt Go w/a 2 1/2" strip cutter. I wanted black sateen & couldn't find any till I found a sheet set at Wally World. Eventually I cut 10" strips & pressed "em, then ran those thru the Go.
