I make some small baskets and bags to sell at a shop in town and the owner asked me to make some wine bags, so this is what I came up with.
This was the first one I made and then stopped in to show it to her and get feedback before making more.
The strips are pieces of old neckties. It was pretty snug and we thought the handles could be a little longer, so I made those changes and then made four more.
The bottom of the bag is a circle, so this project wasn't as simple as just measuring height and width. I had to dust off some math skills. C = 2(pi)r .... remember that? Then making a circle of a specific diameter meant I should really have a compass. During my unsuccessful search around the house I found a roll of packing tape that looked about right. I measured it and the diameter was exactly what I needed. Perfect.
All of the bags have a layer of batting between the outer fabric and the lining.
For perspective, here is one with an empty wine bottle in it, but I think the handles are drooping, because they really are more 1.5" taller than the top of the bottle.
I hope they sell!
