Yes, there are a few drawbacks to spray basting your quilts. And I will never fault anyone who refuses to use them, but I love them. Really, the pros outweigh the cons for me. Spray basting take a fraction of the time as traditional pin basting. And I was surprised how well the spray baste actually held up during the quilting process. I was certain that there was no way this adhesive was going to be strong enough to keep the sandwich together as I manipulated my quilt through my machine. But it does! And, while the quilt may be slightly stiffer than with traditional pin basting, it is still completely pliable. And the adhesive rinses right out as soon as you wash your finished quilt, restoring it back to it's original, snuggly quality.
One of the drawbacks of spray basting is the aerosol. Glue particles will end up in places other than on your quilt (i.e. your floor or furniture if you're working too close) especially as you spray toward the edge of the quilt. Initially I laid paper down on my hardwood floors around the edges of the quilt sandwich to minimize contact between the glue and my floors, but I have found that the glue comes up easily enough if I do get it on my floors. I just give them a little rub and the adhesive comes up quickly and clean.
Another complaint I have is that some spray bastes can gum up the needle in your sewing machine. I have found that this depends on which brand you use. Thus far I have tested out two brands - June Tailor and Dritz. The June Tailor is more tacky and I like how sturdy it feels when my quilt sandwich is together BUT I have noticed a residue on my machine needle when using this brand. I switched over to the Dritz brand and while it's not as tacky as the June Tailor it still does the job AND it doesn't gum up your needles.
If you haven't tried spray basting your quilts I would definitely recommend it. And it's not just for full sized quilts. You can use your spray baste on smaller projects and appliques, etc. The uses are unlimited. Spray basting has changed my quilting life and now I can't imagine basting quilts any other way.
