fusible batting, what did I do wrong?
 

This is my first time using fusible batting, it's Hobbs 80/20. I ironed it all out nicely last night and stitched a couple of rows of ditching. This morning when I went to start quilting again I discovered that the layers are coming unstuck. Was my iron not hot enough, too hot???? Do I press it again or should I get out the pins?

I've only used fusible batting a couple of times in table runners--I am not a fan. I did learn not to start quilting on it right away. Let the item set for a few hours so the glue has time to really set. Did you start quilting just after fusing it? If I were you, I'd try repressing it, let it sit awhile and see what happens. Then if it still doesn't stick, get out those pins.

Be careful and check the item carefully before you start to stitch. I was smoothing mine and felt something between the layer--felt very hard and shaped like an Advil tablet. I opened the layers and it was a glob of glue. Imagine what would have happened if I'd hit that with my needle.

I had the same issues you are experiencing. So once I found spray basting I never gave fusible batting another try.

I use hobbs heirloom 80/20 fusible and lay my quilt layers out, fuse the top. flip it all over and fuse the backing. I usually don't worry about using steam. the layers stay put and i quilt it fine.

I iron it on both sides, hitting places with shots of steam. If it starts to come undone on the edges, I'll add a few pins.

Thank you all for your input. I did try to press again but without any luck.
The glue held in spots but not all over. Now with all of my working on the quilt I have stretched many of the bias edges (the blocks were all made with the strip tube ruler) and I have puffy spots between what ditching I had done. This was supposed to have been a fun and easy quilt intended for a gift. Now it is becoming a real learning experience on dealing with Murphy's law.
I've pinned it and will try to continue that way. Next quilt I am back to spray basting as I have no idea what went wrong here.

I personally dislike fusible batting didn't go well for me either, never used it again. How big is your quilt top mine was a queen size.

It is an odd size. I was playing with a strip tube block in my eq and my teenage son started flipping the blocks around. He liked his design and I figured it was a fun way to make one for him. It is 77 x97 with the boarder. I had purchased a queensized bat for another project but thought it would be an easy way to help stabillize the blocks. If it turns out too lumpy with all of this stretching I suppose the dog will enjoy it.

Yep, I did use a dry iron. I did let it sit longer the second time and I did iron the front and back. It did seem to be sticking at first but then just let go. I live by the water so perhaps the moisture in the air has damaged the glue. Now I am holding a steamy iron over the bocks hoping they will go back in shape as I safety pin it together. I have never free motioned a pinned quilt( this is my 3rd quilt) so it should be interesting.
I have some pieces left that I will try to use in place mats just to see if I can figure out what went wrong. I will definitely stick to spray basting after this.

I have had a similar experience with fusible batting... it will stick in some places and not others. I only use it for mug rugs and other small items because it's really frustrating.

I've used it for smaller projects and I don't like it. I never had any success with it sticking. I have better luck with Elmer's glue.

I'll jump on the bandwagon here. I have never, regardless of application, had any luck with fusible anything. LOL, could it be the operator??

I'm with you on this ... seems like I have issues with everything I try ! But that's o.k., keeps my old brain working as I work out the messes I make :D.

While I'm not familiar with Hobbs 80/20 fusible batting, I can only comment that I use fusible fleece/batting for small projects, purses, tote bags, wall hangings, placemats and table runners and it has always worked well. Sometimes though I will need to press a second time for the fusible material to attach itself to the quilt.

Largest I've used is baby quilt and it did start to come apart before I finished FMQ. Spray basted worked better but I was too messy with it!
Would add that I've gotten into trouble with bias edges on a quilt--particularly larger blocks,so now I starch before cutting those and run a seam on outside edge before putting on the frame--saves headaches.
