Years ago, I made several Frostline kits - down jackets. The packets of down were very compressed into narrow packages (maybe she could do this for you) Then when you were putting it together, you had a packet for each section - channel, and you carefully squeezed the down out of the plastic bag it was in, and into the channel. If she was willing to "package" the down, it would make it much easier for you. I don't know if Frostline is still doing business, but their products were very good - my daughter and I wore the jackets and vests for years.
