I'm restoring some old rockets that have original shock cords. What do you guys recommend for shock cord replacement material for small stuff (C size and less)? Craft store eleastic, or some other cheapo replacement material?

I have been thinking about using fiberglass rope for a shock cord like the stuff McMaster-Carr (https://www.mcmaster.com) sells:
Catalog number 8818K42 Braided Fiberglass Rope Seal 1/8" Diameter. Looks like it might work and its considerably cheaper than Kevlar. If the fliber glass rope is too friable I could always ewncase it in PTFE sleeving. McMaster also sells a fiberglass sleeving that could be used to protect Nylon or Kevlar shock cords.
