These ideas for packaging jam and other preserves would be great for gifts, they use vintage jars with labels using a simple font.
Vintage jars can be picked up in charity shops and flea markets, just make sure to carefully clean and steralise them before using.

If the jars don't have lids they can be sealed using waxed circles which, when placed directly onto the surface of the warm jam, create an airtight seal. The jar can then be finished off with a decorative paper jar cover.

These examples can be found on the  Country Living website.

My sister is an expert maker of pickles and preserves, and made a large batch of red onion marmalade with balsamic vinegar for consumption with the mountains of cheese at her recent wedding.

While she couldn't quite remember the exact recipe, it was similar to this red onion marmalade recipe. I would highly recommend it as an alternative to using brown onions.

She also designed and made some lovely labels for the onion marmalade and two other chutneys served on the day, she shows how to make these labels in this blog post.

The matching jars looked great on the tables at the wedding, you can find similar jars here.
