Sewing a footbox in a synthetic quilt
Apr 13, 2021 at 8:09 am #3708772
I’m in the beginning stages of designing/ making a 50 degree synthetic quilt. I think I want to have a closed footbox and like the simplicity of the MLD Vision foot box (pic below). Any help on how I would go ahead to build and sew this? Other recommendations for a round or rectangular vs. just a simple drawstring are welcome as well.

The first quilt a made was insulated with 3.6oz Apex and had a sewn footbox, so similar to what you are thinking of. I read about trapezoidal end plugs and thought that was very clever: shaped for how your feet splay out when you lie on your back. What I didn’t think about is that I usually sleep on my side! ; ) It doesn’t seem to matter because the fabric in the footbox can conform to different shapes. So my suggestion is to sew a round or square foot plug, or maybe rectangular with the long dimension oriented horizontally if you sleep on your side.
I haven’t tried a drawstring style: I like the simplicity of a sewn end. If it gets too hot, I pull my feet out, so I haven’t missed being able to completely open the bottom of the quilt.

You can look for my threads here on how I did it as well as several posts on the MYOG subreddit. Lots of info. I’ve done circular as well as a hexagonal end cap for my quilts, I don’t think it matters much as Bob points out. The image you show gives a pretty decent way to avoid cold spots by minimizing the seams although that can result in the need for ordering more insulation than would other wise be needed.Apr 13, 2021 at 10:54 am #3708785
Thanks for that Bob! I like the simplicity of a sewn in box as well. I’ll look into some footplug options. Would you sew in the plug when the quilt is turned “right side out” or do it when it is “inside out”. Appreciate you insights.

Thanks Michael. I’ll review those MYOG threads. I’m new to DIY stuff. It’s been really fun and rewarding. For the image I posted, how would one sew that? Thx.Apr 13, 2021 at 11:42 am #3708793Michael BBPL Member

I basically sew the shell and liner into “tubes” since my foot box goes up about 24″ (just behind my knees), and sew the caps into each separately. For the synthetic quilts I made, I sewed the insulation to the shell and the shell cap, then sewed the shell+insulation to the cap+insulation, then attached this to the assembled liner+liner cap. I left about a 6-8″ opening in the middle of the liner seam that goes between my knee and the cap, which is where I pull the assembled quilt right side out, then hand stitch it closed there with a blind stitch. You could easily sew the area closed with a machine, I just like the cleanliness of the blind stitch there. Either way is not a big deal, since that area of the liner is not a highly visible spot once the quilt is done. The liner in the footbox area floats in this type of construction since it is not attached to the insulation in that are, but I’ve not found that to be an issue.Apr 13, 2021 at 1:12 pm #3708808
Thanks for the info Michael. That helps a tonne!
