I've decided to tackle a down quilt as a project and I wanted to know what people typically use for seam allowances on the outside edges of a quilt (keep in mind I'm learning to sew still). Also, about how much allowance will I need to add a shock cord channel at the head?Mar 20, 2011 at 11:06 am #1711621
I normally use 1/2" seam allowances. If you are making a drawstring/shockcord tunnel, i'd make that at least 1/2" wide, maybe more. Let's say 5/8" wide. so you need to double that,then add at least another 1/4" to fold back under so the raw edge is not exposed. So that is 5/8+5/8+1/4= 1 1/2" past the point where the line of stitching will be. I hope that makes sense!Mar 20, 2011 at 3:21 pm #1711713
We had to get a new sewer last year – boy, was that ever expensive! But at least now, th….
Oops! Sorry! Wrong type of sewer! <>
Okay, seriously Jeff, Is this your first project sewing nylon material? A down quilt is quite a project, and if you're not familiar nylon, you might want to start off with a more limited project – how about a pack cover? Or a pair of gaiters?
Are you doing a sewn-thru or baffles? You might want to check some of the outdoor fabric places for patterns – these would make your job a lot easier!
I would recommend a 5/8" seam, then add whatever foldovers, etc, you're going to need. A shockcord tunnel could be anywhere between 5/8" to 1" (times two if it's folded over). Remember to include fold-over seams at the ends of the channel!Mar 20, 2011 at 7:50 pm #1711841
Everything you want to know about sewing a quilt and more…
Bear in mind these instructions are for a sewn-thru construction quilt, a baffled quilt will be a bit more cutting and sewing work. Thru-hiker.com has a brief instruction page for making a baffled quilt if that's your aim. Pairing the two write-ups together is a wealth of info.
Best of luck, a quilt was my first major MYOG project, but I've been sewing on and off for the better part of my 25 years, so it's certainly not my first time behind a machine.Mar 20, 2011 at 9:22 pm #1711881
I would recommend 1/4 inch seams. Having repaired dozens if not hundreds of packs, sleeping bags, tents, etc. As well as having built scores of backpacks in the industry, 1/4 is the norm. Sometimes a little more (3/8 often in zippers), and rarely a little less (for seams that are taped.)Mar 20, 2011 at 9:45 pm #1711891
Thanks for the advice. I'll be making a baffled underquilt. Right now I'm just planning it and finding as much information as I can on construction. I'm going to start off with sewing stuff sacks and tarps and work my way up to the quilt.
