To Steam or Not to Steam?
 

For those of you who spray baste your quilt sandwiches together, do you use steam when pressing after the spraying? I'm wondering if spray moisture could loosen the adhesive?

I don't press after spray basting, just smoothing with my hands seems sufficient.

Yes, and I've found that pat-patting the layers (bat to the backing and then the top to the bat) avoids all wrinkles for me. I end up with a very smooth quilt rather than try to stretch it flat or measure precisely. (you can trim afterwards.)

Ditto! I spray starch and steam press before sandwiching to help with spray basting process. Works for me.

This is what I do. Steaming heavily would probably loosen the glue a bit. I don't really know because I haven't done it.

I also never press after spray basting.

I usually do not iron after spray basting but if I have not been careful trying to FMQ or embroider on the quilt I have to iron. So far the pressing has not hurt the sandwich.

I will press after spray basting but I do not use steam. I like to make sure everything is smooth and wrinkle free so I press the back first and then the top.

Someone here posted this tip. I tried it and it's the best way I've found to smooth a quilt while spray basting.
If you have the long Quilter's Slidelock use it to smooth. No pressing needed. Only takes a couple of swipes per side. I don't use a rotary cutter without my Slidelock so now it has two important functions for me.

I've seen a video where some one uses the side edge of a 24" quilting ruler to smooth the quilt fabric to the batting while spray basting - looks like a great idea. (So, no Quilter's Sidelock is required for this technique.)
