So I have a Gossamer Gear Rukus pack which I'd like to add some grosgrain attachment loops to the sides and bottom to strap things and for compression. I'd also like to add on a top strap to go over the cinch top. Pretty basic I know, but this would be my first time modifying any gear or sewing in general.
Can I sew some grosgrain loops and webbing right onto the pack fabric as it is without opening up all the seams? I know it would look better and be stronger undoing the seams and restitching but I'm not comfortable enough doing that yet.
Any advice in general?
Thanks!
