instead of spray basting maybe it would be better for you to try the fusable batts so you only iron your sandwich together instead of filling your lungs with noxious fumes. i have even used a regular batt that i put fusable web on myself. personally i go ahead and baste my projects i'm going to quilt on the little machine, it doesn't take long, and seems like lots less hassle to me...but i do avoid noxious fumes at all cost.
