About to sew up a 3/4UQ tips please!

[Gsx-rboy750]

So I had bought a used 3/4 UQ a while ago for a good deal. It does have its issues which include leaking, not too wind proof and I think lack of down for my climate or at least liking..
I am in the process of making a new cover and will send the cover to another person to stuff with the old down (I was told it was 850) and overstuff with some additional down.

I have read every instruction manual I can find so another link probably wont help to much.

My question is pretty specific.
I have my larger piece cut at 64x58 currently and the smaller piece cut at 60X (debating between 48 and 50)
I plan one running 11 baffles that are 2.5 inches height from seam to seam.
I will end the baffle before the ends by about 0.5-1 inch
I have a pretty strong sewing background and am not doing the stuffing.
My main question is what should I make the width of the inner smaller piece 48, 50,52 compared to the 58 outer width?
And is 11 baffles at 2.5 depth sound groovy.
Thanks in advance for any help.
I guess I don't mind a slightly wider quilt and warmer 3/4 as the girlfriend's kick dog and I are hammock sleeping buddies.

I would go 48. The larger the difference in the inner shell vs outer shell, i.e. differential cut, the less likely you are to compress your down, resulting in a more efficient UQ. Have you used Catsplats UQ calculator?

That should help.

What about any tips or tricks that a excel chart may not provide?

Measure twice, cut once. Mark everything out while you are cutting. Work slow. Don't take short cuts. Nothing you probably haven't heard already.
I actually sewed the ends of the baffle wall material to the shell, that way each baffle is closed so no down can migrate. I sewed darts in the outer shell down the center of each baffle about 6 or 7 inches to account for the difference in widths. I sewed one small pleat in each corner to account for the length differential. You can use pleats or darts. Pleats are easier, darts look nicer, IMO.

For what it's worth: on 3/4 UQ you can go a lot narrower, and I think this helps the quilt sit tight to the hammock (less area for a gap to occur). Especially if you run shockcord along the long end.

I've made my quilts 40" wide and thats plenty. A 3/4 quilt will follow your body a lot better than a full length.
