I'm considering selling a large quantity of yarn on eBay, which would be best to ship in plastic bags. I've received goods in such bags, but I've never shipped in them, and I'm seeking advice on how to choose the right product.
On eBay I see listings for bags made of several different materials in different thicknesses. How do I decide which is most appropriate for me?
What about size? I want to get the kind of bag that has no edges, just an open end with a sealable flap. No one seems to be selling those. All the products I see on eBay (and Amazon) are shaped like envelopes, with dimensions given as length and width; my packages will have length, width, and thickness. How do I tell which size bag will hold various amounts of product?
My guess is that I should add half a package's thickness to its length and width, plus another inch in each dimension for safety. So... six skeins of yarn make a stack about 9x7x6 inches, and I'd put them in a 9"+3"+1" = 13" by 7"+3"+1" = 11" bag. But that's just a guess... I'm hoping for something more authoritative before I start spending money.
