I am ready to use 505 for the first time, have read and followed instructions. my question is do I iron my sandwich? Instructions do not say to do so, but I could swear I saw a tutorial on it that said to iron it to set it. Of course now I can't find the tutorial! If I iron it do I use dry or steam? Thank you for your help.

I never iron my quilt sandwich when i use 505 spray. It is a great spray baste that does not gum up your needle. I use it for everything.

no, just spray one side, smooth your fabric over the batting, flip it over, spray the other side- and smooth the fabric over that side- some people pin around the edges to keep everything secure *especially if it's a large quilt*

I never heard of ironing after spraying, and I use the spray all the time. I do wear a mask when I spray and take my glasses off too.

and make sure you get the 505 basting spray that isn't permanent. they also have a permanent spray. different color can but read it before using or buying .

You do not need to iron it. I never ironed when I used 505. However, some people like to iron the quilt sandwich to make it flatter and therefore easier to quilt, no matter what basting spray they use. I don't believe ironing affects the 505 in any way. If you are uncertain whether or not you want to iron, I would suggest making up a test sandwich to see if ironing affects ability to reposition, etc.

Thank you all, I'm off to start quilting.

I have always ironed when using an adhesive spray but now I'm wondering if I should. It didn't seem to matter one way or the other so I'm guess it's just preference. I iron everything!

I compromised, used a really old and heavy iron, no heat. seemed to bond a little tighter with the extra weight on it.

I will iron the back on a bigger quilt, just to make sure it's all nice and flat. It's easy to reposition if it's has gotten a little wrinkly. I don't ever bother with pins though.
