HeatnBond HnB36 Fusible Interfacing Ultra Lightweight, 15" x 3 Yards, 1 Pack

Is this a paperback 2 sided fusible?

Could this be used on lightweight silk taffeta, to prevent fraying and add strength to seams?

Our dog snagged my hubby's knit shirt and made a small hole. Would this work as a "soft" patch on the inside of the shirt so it doesn't get bigger?

Can I use this to reinforce inner thigh seams?
