Those bits in the pictures are probably fabric, or some other fibrous material (fireproof), that keeps hot gas and any "sparks" from the mortars from hitting the canopies and/or the shroud lines. They *might* be pieces of a single sheet (per parachute), but I suspect that they use multiple, smaller sheets that are packed so as to partly overlap each other, because several smaller sheets would be less likely to become--or stay--tangled up in their parachutes.

Yes, that's kind of what I thought it was probably, too. Only makes sense that the 'need' to do that would be there and to use multiple layers of some kind of flameproof material. The chutes themselves I believe are 'bagged', and that bag is then attached to the pilot chutes, so one would assume a decent amount of protection from those bags. But, as all us old-time rocketeers can attest, it is sooo easy for a bit of heat or spark to get past the best 'chute wadding' and cause heat damage to a canopy. With 'models', that's not necessarily the end of the world. With a manned space capsule, it's a different story! Earl

Back when a buddy and I were kids, we just used plain paper toweling as wadding.
I came back down smouldering, which we just put out by stomping if it didn't self extinguish. We weren't about to spend our small amount of hobby dollars on flame-proof boraXed toilet paper.
