Not just the glue, but think how you will quilt the beast if you are quilting
on a DSM. Also, think about how you or the recipient will wash the quilt.
Will it fit in the washing machine? I use Warm and Natural or Warm and White
all the time and it's pretty warm. I've never doubled the batting.
When it gets to -30 I might double my quilt but I will never try to quilt
double batting. That might finish me before I finish it.
