I think I have it down to just under an hour for a bigger quilt. But I don't do it that often so that seems like a long time some days but in comparsion to the amount of time it takes to finish it, I love it. I used to hate the pinning and sandwiching so the LA is great I end up with much less issues on the back.
We have the zippered leaders but very rarely take them off... only when we get frusterated with a quilt so we take it off, do a different project and then put it back on to finish it later.
My mom has a quilt on there right now so last weekend I made a baby quilt on my regular machine and it was killer! Oh well, I have 2 more tops ready to go on the rack so I think i have a busy weekend ahead of me.
I have to have 1 done for Monday (it's a guild challenge)
