Hey Ryan! I totally understand where you're coming from!! I love finding great designs like this one that look DIY-able, because we here at Curbly--even if we can afford to buy such things--LOVE the challenge of making it ourselves. So, we try, and if we fail, THEN we buy the original! LOVE your website BTW. I have a feeling I will be scouting it out for other such fabulous items. I hope you don't mind! ;)

Yup, you're right, optimist. It actually makes perfect sense!!

Without having made one, just looking at it, I suspect that you would not be able to make it like that as the fabric would be too stiff. I think you would have to start from one edge - stitch two pieces of fabric on the short end, then do the same with the other two pices. then (1)put one double layer on top of the other and sew together the middle two pieces at a distance of half the circumference of a bottle plus a bit of ease. Then (2) stitch the two original pairs (ie top two and bottom two) together another half circumference along. Repeat processes (1) and (2) across till you have the four bottle spaces, then stitch the ends same as the first seam.  Phew! hope that makes sense.
