Stacking UQ questions

[MT]

I have 2 UQs, one is a sewn through 50* 2/3 length quilt and the other is an 0* Incubator. I am looking to sack them to try and get down to a lower temp. for winter camping.

Would it be best to stack the sewn through next to hammock or on the outside? My thoughts would be to have the sewn through on the inside, or could this cause gaps?

Another question would be, how to stack UQs and not have them shift on you? Should I use cloths pins to keep the edges lined up or is there a better way of doing things?


Thanks,
