I was wondering if anyone has taken a down throw blanket and turned it into a underquilt. How did you like it? It seems most are 700 fill and I do mostly shoulder season camping would it be warm enough for 20-30 degree temps pair with a 20 degree TQ? Thanks folks happy hanging

While I know a lot of folks have made top quilts out of the Costco down quilt for instance, I've never heard of someone trying to make an underquilt out of one. An underquilt would be a more technical project, in that you have to somehow add suspension cords and make the cords adjustable because you need to be able to shape the underquilt to your hammock so you don't get cold spots. I think with underquilts it probably makes more sense to buy one from one of the cottage vendors that's already got them dialed in. My personal suggestion would be the Hammock Gear Incubator in 20 degree, either the Premium or the Economy version.

I've seen DIY build threads on Reddit for the Costco & similar down throws to make them into top & under quilts. I have a tq I made myself several years ago and it's great. Channels for suspension can be made with grosgrain ribbon.

A DIY UQ for a gathered end is on my list of projects still bouncing around my head (vs in some stage of actual production).

I am making one that uses the OneEagle "Banana" style as a pattern. I have been putting it off - not looking forward to the feathers all over the house as I cut the Costco Quilts to fit the pattern. I sew a flat seam either side of where I need to make a cuts, then cut in-between the stitch lines and use the surger to finish the cut edges - oh, and then get the vacuum going. It is simple and the top quilt "flaps" will attach easily. I will do Pics when I get it done.

Thanks to everybody I am doing a little more research on this. I’m still thinking of making my own but time seems to be slipping away before my trip . Mirth and grandma l I would love to see pictures to get an idea.

I finished this afternoon. It was pretty easy. I took the pattern from a "store-bought" One Tigris brand under quilt. It is their lighter weight model. I used fabric from JoAnne's. Pre-quilted with synthetic batting and nylon in and out. I started with 3 yards - it is 60 inches wide - 58 after I trimmed off the salvage and excess batting. Pretty easy - one main bottom seam and some finishing stuff. It has a simple elastic cord at each end with a small biner to attach it to the hammock.
Here are a few pictures.












My next plan is to make a pattern that is share-able.
Contact me if I can help. I live in the western Mpls area.

That’s a great job, Lori. I wish I could sew like that.

+1. That looks Awesome grandma L. In your opinion how adjustable are the elastic cords you attached

Oh, very! They can be easily added to or reduced to fit a particular hammock. Next I want to try to use a Costco down throw to make one. Might get a little feather messy.
If you are local to Minneapolis/St. Paul - I would be happy to help. send an e-mail.

I’m somewhat local i live down by Rochester. Thanks I may take you up on that

Here's my winter projects thread from a few years ago. The TQ is still going strong although it looks like I need to firm up the stitching at the top of the footbox where it opens. Maybe a bartack for reinforcement.

The quilt is almost at the bottom.

Today I did a Down Underquilt from a Throw. Pretty easy - I just put edging on all 4 sides of the throw, then tabs on the 4 corners that made the ends to hook to the hammock rigging. And, I put draw strings in the edging/casings at the head and foot. That way they could be gathered to make a toe box and not be cut off. I did the elastic long enough to hook to the hammock rigging and keep the Underquilt side edges tight but still have "give" to get in and out. No open seams and no feathers around the house. It is only 70 inches long but no need to insulate the hammock ends.

It looks like Grandma L's down throw UQ would be exactly what you would need to do. I would be careful trusting the costco throws down below 40 degrees F as they're sewn-through rather than baffle construction. Sewn through insulation generally doesn't get rated below 40F based on what I've seen in the market. If you're a warm sleeper and you have additional insulating clothing you may be able to push it lower but I would recommend trying it out close to home at those temps before trusting it in the BWCA.

That looks like what I need thanks for posting grandma L. This will be a winter project after things settle down at home. And also thanks to Adamakbar for the temp rating tip

If you want to take the time with a seam ripper you could always rip out either the horizontal or vertical lines of stitching. It'll lessen the heat loss from sewn-thru baffles a touch.
