Fab stands for fabric and fabulous!
I found this little gem at the fabric store while I was shopping for fabric for Christmas gifts.

The uses include - basting seams and matching plaids, positioning ribbons, trims, and appliques, basting hems and zippers, and tack down seam allowances to keep them from moving or flipping over when sewing.
AWESOME!!!
No more ironing and pinning hems :)

I started making bags that are a combination of felt and fabric and the beautiful thing about felt is that you don't have to hem the edges! It's not that ironing and pinning is difficult, it just doesn't excite me!

You use it just like a regular glue stick - rub on area...
You can sew right through it and it washes out.
