I press open but sometimes things still get tangled, and I’m a bit OCD so I spend the time to get the seams going where they should. As such when the time comes to do the final press of a top, I pull up my chair to the ironing board, grab my seam ripper and start the process. For me this helps make sure that not only are my seams going where I want, but also helps me see if I missed anything, if anything is coming up short etc. , allowing me to correct any issues before it get on the longarm or into the hands of the recipient.
