I want to make a baffled down quilt with a drawcord footbox and have been thinking about how I will finish the edges. I would like to topstitch the sides for the most streamlined appearance but can't get my head around how to do it. Has anyone been able to?
In the past I have just used a rolled hem a la JRB quilts, but while it works well, I much prefer the look of internal seams/top stitching.
I've seen this thread where Tim Marshall (Enlightened Equipment) has described how he finished his edges: http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?forum_thread_id=31403
He describes this as "top stitching", but if I understand him correctly it isn't top stitching per se, but is rather what is often referred to as an "edgestitch" (see http://www.backpackinglight.com/cgi-bin/backpackinglight/sewing_primer_straight_and_top_stitch.html). Tim, please correct me if I'm wrong.
It seems that Tim folds the unfinished edges of the liner and shell into the quilt and then stitches close to the folded edge. While this means less fabric sticks out from the insulation, it isn't as streamlined/hidden as a true top stitch. And I would be worried that there isn't a reinforcing line of stitching as well, and it could be more prone to down leakage than the rolled hem. One workaround could be to sew the unfinished liner and shell edges together, then push them into the interior of the quilt, iron the edge and then sew it like Tim does - that would be reinforced, but still leave overhang.
On the other hand, a lot of production baffled quilts/sleeping bags have top stitched/streamlined edges - any idea how it is done? Perhaps it requires a machine/skills the average MYOG'er doesn't have? I just can't get my head around how you could do it because turning the shell inside out is prevented by the horizontal baffles.
Any advice appreciated!
