VERY thick blanket!
 

Ok, I am very new so I apologize if this is in the wrong place - Please put it where it needs to be if it's wrong!

I need some advice!

My project is a little unorthodox, and it's not exactly a quilt, but I figured the method would be similar.

My husband and I will be living in a tent for a while - not sure how long - so I am making an extremely thick, wool, 2 person sleeping bag. The wool batting is 4" thick, the bottom side will be thick hemp canvas for durability, the top will be some type of thick cotton, and the interior will be probably linen. I'm also making a "sheet pocket" that we can remove and wash like a regular sheet. The entire thing laid flat will be about 108"x75" and will be folded to 54"x75" (we're both pretty small). I'm also debating between an ridiculously giant zipper and a row of buttons as a closure for the open side.

Now, I know I need to tack the layers together to hold the batting in place and keep it from being a big, billowy mess, but how in the world do I baste a 4" thick comforter? Are there pins that enormous? Not to mention this thing is just really really big, so I need a way to hold it in place while still being able to work on it.

Should I just lay it all out and work from one side? Wouldn't starting in the middle be better with everything held down?


Sorry for all the questions - if this is something no one has any clue about because it's so weird, I understand, but I'm really stumped on this one!



Thanks so much!

Wow, what temperatures are you planning to sleep outside in? Is the wool lightweight and puffy or is it dense? Most sleeping bags for extreme temperatures are very light weight and soft - check out a camping store. You want to make a sleeping that will dry quickly, it will get damp/wet from sweat, humidity or possible rain leaks AND should be dried daily.

I would suggest using ties instead of sewing. Remember the more air pockets, the warmer it will be and it will also not overheat you either.

To join the layers, use 2 zippers which meet or almost meet at the bottom middle, this allows the top and bottom layers to be totally separated - makes drying time faster because it is only half the thickness. This also allows if the bag is too warm for one of you, then you can unzip your side only. Most people make a double sleeping bag by joining two single sleeping bags - very easy to put together and take apart.

Use a woolen hat! Keeps your head warm and your body warm too.

If I was planning this adventure then my sleeping bag would be lighter than needed. If I was cold, I would cover the bag with additional blankets for warmth. I would NEVER be making sleeping bags. I would be purchasing two single sleeping bags with the appropriate temperature rating, and be making and/or buying the extra blankets. I have family members which camp during the Winter when it is -40F, and their biggest complaints are from being too warm or unable to dry their equipment.

I hope this helps.

Are you sure you wouldn't just want to zip two sleeping bags together as a base to start? As Scout campers, our bags are warm, lightweight and dry easily. Then you can focus on a cover and liners instead of reinventing a bag. If you do decide to make a bag, you could get long long zippers from army/navy surplus bags.

I have no idea how you would make it. I am just content to stay in my warm house. Sleeping outside in any weather is past my comfort point.
Good luck.

for the sewing to hold it together, zipper, etc- how about taking it to a saddle shop/shoe repair shop or something along that line. They have realllly heavy duty machines. They might also sew some lines on it that will hold it together. Just a thought. Canvas awning place? Boat tarp maker?

Interesting project!
Take it to a longarm quilter; these machines were originally made to do bedspreads/comforters.

I agree with those who recommend you take this project to a long arm quilter who can do this properly... also I recommend you put a plastic shower curtain or some kind of liner to protect you from dew or rain soaking into the comforter blanket..

I would suggest buying two Artic sleeping bags and zipping them together to make one giant one. They have a "waterproof" cover to keep out the dampness and plenty of padding to keep out the cold. I don't think you can successfully put the bag you are thinking about together on a domestic sewing machine.

Buy a double person sleeping bag! They are really nice and you can snuggle in them.
