This method is really easy.The best part is that it is easy to reposition if there is any shifting.There are also no pins to remove while quilting.So there will be less stopping while going the free motion work.
You will need to use it in a well ventilated area and protect the area because the glue seems get all over.
It can get quite costly though.I would save this method for large quilts which are are harder to baste and quilt.
Always have the batting and backing about 2 inches bigger than the top.
I used a panel for the top and two way pattern for the back.
Iron out the creases on the top and backing fabric.Unfold the batting and ease out the creases with your hand.
Line your work surface with newspaper, an old shower curtain or fabric.
Place the back right side down and smooth out.I used clamps to hold it down and worked in smaller sections.
Shake the can well and spray onto the wrong side of the backing fabric.
Place the batting over the backing.
Spray onto the batting and place the top onto the batting.Smooth out as you go.
If you are left with any creases, carefully lift the fabric and place down again smoothing it out.
Check the back for any creases and smooth out if necessary.
When you are sure there are no creases,secure the ends with safety pins.
