Working on a quilt. The primaloft is a downy material between 2 layers of poly something. My question is: is the poly something only used for shipping or is it sewn into the quilt too? Thanks.

When I made my underquilt for my Hammock I used Primaloft and left the lineing material you mention on because when I did some experiments with the sewing machine beforehand, I found the the feeddog/foot had a tendency to not treat the Primaloft well. (Personal experience and preference!!!) Thus I left the lining material on and sewed it right into my underquilt.

Try it with a couple of scrap pieces of materials sewn together on your machine and see what works best for you. You may find that you feel comfortable without the lining material. You are not going to sew any of this at any fast speeds as you have to compress the Primaloft as it enters the sewing area so find out what works for you. I do not think leaving the material in changed anything about the underquilt as it weighs next to nothing anyway.

Is the poly-something sort of like a single sheet of white tissue and stuck to the insulation? If so, it is batting and is sewn into the final produce.

Thanks TOG and FD. FD, it is tissue-like but not attached to the insulation.

I would use it, but if it is not attached, it is your call. As TOG notes, tt is harder to sew without it and the material is extremely light.

I went and weighed it. 3yds of 3oz should be 9oz. It weighs 17oz with the 2sheets of "tissue."

TOG, what material were you using as a shell?

Thanks again for the info.

The three oz per yard is an industry measurment for 1 square yard- if your stuff is wider than 36 inches, it will weigh more per linear yard.
Take the width (in inches) times the length (in inches) then divide by 1296 (# of square inches in a square yard) now you know how many suare yards are in your piece of stuff, and multiply that by 3 to see if you get the total weight you measured. HTH, Betsy

Thanks for the nudge. (108x60)/1296=5 sq yds

5x3oz=15oz. Maybe my scale is off a bit. It weighed in at 17oz.

Thanks all for your patience with a rookie sewer.

Don't forget to post a pic or two of the finished quilt. I love to see people learn to make their own gear. Some of our best gear - tarptents, Speer and Hennessy hammocks, cozies - has come from hikers turned DYI.

My only finished project is a 6x10 sil-nylon tarp.

Been working on a goretex bivy sack for uhhh.. well a long time. I am stuck at the zipper (as in trying to find enough time to do it right). Looks good so far.

I expect this should be easier. Then I can return my borrowed sewing machine.

I think I took the sheet off when I made my quilt. I had foot problems with the machine also. My mom helped me and she swore like a sailor when the foot got stuck!

I used some $1 fabric from wally world. The outside is very water resistant and the interior is a thinner weave nylon. Stuff sack and quilt weigh 2lbs. I used a really dense primaloft. Got it from thru-hiker, and I belive it was the primaloft sport 6oz.

I removed the scrim layers on our 2 person quilt. I had the same sewing problems. That aside, the quilt has help up great for almost 3 years now. I did very loosely quilt the primaloft, being careful not to compress it and only to help stabilize it.
Best Regards,
