I use system three epoxy for everything. It's pretty expensive, but It's awesome for any laminate bows, and I have plenty of it. So put some on the back, lay down the fabric, apply a little extra on top of the fabric, and work it in and smooth it out with your fingers ( wear gloves). Wrap the fabric around the sides just a little, when it's dry you can just sand the edges smooth. That's what works for me anyway.
