I used some Gedifra Ayalayarn and crocheted a jar cover. The openwork pattern I used was very simple: 2 dc, front post dc, 2 dc, chain, cross dc over two stitches, chain, and repeat to end.
Crochet is great for this kind of project, as you can check your work will fit the jar, as you go along. Once I got to the top of the jar, I added a 3 chain mesh to run the ribbon through.
Gedifra makes their yarn in Italy and I really love their linen blends. I snagged a big lot of Ayala yarn on eBay some time back and still have about 6 skeins - all different colors. Waiting for inspiration - or a long romp thru my Ravelry queue.
