Normally I do throw size and smaller with my DSM and then it's only Grids on the slant.
I did do a grid on twin size for a Xmas present this past Xmas. Me too, never again.
My machine is 14 yrs old, per my service person the longevity of my machine is 10-15 yrs.
I do have a full size top done going to the long armer in a couple of weeks.
I probably send one a year to the L.A.
