Hi,
I am looking into making a two-person quilt and have noticed that both insulation and fabric come in a standard 60 inch width, meaning that it would not be wide enough for two. What is the best solution for this in terms of sewing and buying fabric, and maybe some of the potential complications of not working with a continuous pieces of fabric/insulation?
Thanks,
Sven

Hi Sven-

It complicates things only because it requires a long interior seam.  Usually folks locate the seam vertically so that it falls between the two sleepers. 

Sleeping bags have the same fabric-width issue which causes them to be made up of multiple panels.  This isn’t too big a deal, but does require more planning than is typical for an easy quilt project.

One way to make joining panels easy is to first attach the insulation to the fabric panels using an overcast stitch which flattens the seam (see attached pic).  This is a very fast and more effective alternative to basting as long as you can avoid insulation stretch.  The now flattened seams of the panels you are joining are easier to deal with than the awkward insulation bulk of multiple layers without overcasting.

Synthetic insulations stretch under pressure, and folks who are new at working with battings typically report problems because of this characteristic.  There are a lot of different ways to solve this issue, all of which have in common a way to notice when the insulation is no longer lined up with its corresponding fabric point.  Popular ways to deal with stretch include liberal pinning, basting, overcasting, and temporary lamination with a water soluble spray adhesive.

The stretch of insulation varies with grain direction.  Sewing across the grain increases stretch and vise-versa.

Seaming probably decreases the efficiency of the insulation as loft is decreased at the seams.  I have not objectively evaluated this problem.  Nevertheless as a rule of thumb I minimize interior seams for ease of construction and to maximize wind and water resistance by minimizing needle penetrations and if this also happens to maintain insulation efficiency so much the better.  And for items with multiple insulation layers offsetting the seams would also help to keep things lofting evenly without too much bother.
