I was wondering if someone on this forum has experience with sewing on zippers and can advise me.
I have this Aricxi mesh bivi:https://www.aliexpress.com/item/32833751469.html
...actually, it only weighs 213g without the cord.
I also own another older one, different brand, for many years, great to use under shelter or a dry night. The zipper is on the top, for easy step in/out.
Under a tarp, I would like another zipper, for side entry/exit, a bathtub like this sketch:
I don't know anything about zipper sizes, found this #8:https://www.ebay.com.au/itm/Medium-Ligh ... 1659197833
Don't know it's weight per metre, did see 50g/metre for #10, plus I think 38g for the zipper.
Considering that the bivi is only 213g, want the zipper to not add too much to that.
My first question is, should I go for smaller than #8?
Second question, it states that the zipper is designed to be sewn on a curve, but what is a practical smallest radius?
Third question, does anyone know someone in Perth WA who does that kind of thing, like sew zippers on tents?
OK, a fourth question, does anyone know a vendor in Australia, apart from eBay, that sells suitable zippers online? Or even local in Perth?
