DIY UQ Baffle question?

[gargoyle]

I am struggling to understand this too. Looked at Jeff's project a lot, what I don't get is how does the baffle attach to the other side of the quilt? I've thought too, what if you staggered the baffles and put one on each side of the quilt, letting them hang in the space between the baffles on the other side when the quilt is assembled?

The purpose of the baffle is to prevent the down filling from moving .
They need to be attached to both the inner and outer shell fabric.

If they were hanging loosely inside and just stitched to one layer the down would travel and end up in one big ball, creating cold spots.

You can sew all of one side of lets say the inner side of the quilt, roll it up to make handling easier. Expose one row of previous sewn on baffle, sew that to the outer side of the quilt, creating the baffle or tube. Roll back again to the baffle and repeat..
Or sew each baffle to both as in dblc's diagram.
SYOQ.

End result, you need enclosed chambers or baffles to keep the down from moving around.

A loose filled quilt with no baffles will become a large pillow.

Ok! Thats great info....2" will be the next quilt! Do you use bug netting or somthing else for the baffle material?

I used bug netting but all suggested will work fine, I just wanted something soft.

Thaks Dblcorona, et. al., I'm beginning to see the light! The pics of Jeff's quilt make it look like the baffle is a loop that is sewn to the bottom layer only to form a tube. Guess that would work but then the top would move around. So what is a differential baffle?

No the baffle is sewn to top and the bottom or it wouldn't work.

differential refers to the top and bottom being slightly different -width/length from the other- this allows one side (usually top) to be pulled tight against the hammock bottom without crushing the down up against it, due to the bottom layer also being pulled tight. hope that helps, KM

I feel your pain Samiam2714, I am putting on the final stitches today.
The Karo was a challenge but it gets easier near the end....good luck

Backtrack, one thing to keep in mind the thicker the baffle the more down you will need. I thought 3" after sewing would be ok but on a full size 76"x47"
I have 2 lbs 2 oz approx of down loaded I'm hopeing to leave it at that but if
I were to do again 2" would have been fine I think.

Thanks PKT I am done except for the filling with the bottom but I just need to do almost everything for the top quilt I am really excited to see it stuffed and hang it to see how I did it looks amazing and am really happy with it. You should put up pics of yours. If you finished.

During the future cold and dark months of winter, I hope to find time to complete a summer underquilt. All of these hints will help a lot
