It worked well for my needs.
I bought the 1/8" shock cord to complete a major overhaul on a pack. It zigzags across the back to hold a sit pad, and there's more on the outside to hold the random stuff during a trip.
I think it's great for packs. Might be a bit week for an under quilt project though.
I bought this to use as draw cord on a quilt and underquilt. Excellent product that works as intended and was delivered punctually.
Great pricing, fast shipping.
worked great in my underquilt
