Here are several food items and some packaging ideas from one of my favorite cooking blogs.

Gifts from the Kitchen

Lots of good ideas on this website. I love to use cookie sleeves and decorate them.

I forgot to add that I like to wrap boxes of cookies or mini-loaves in kraft paper, tie it with twine, and seal it with sealing wax stamped with my initial.

It depends on how busy you want to get with the decoration. :) When you mentioned your variety of goodies, I envisioned a whole farm out of cut and glued construction paper. The loaves would be a ranch house, barn, tractor shed, maybe even greenhouses. Bars would be stacked like hay in a pole barn, a manger, a wagon. Cookies would be stacked and formed into a silo or two, a windmill, a watertower. Canned jars could be tractors, cars, planters, fuel tanks, etc.

The same kind of idea could be a North Pole scene, or a creche, or a railway station, etc.

Rhizo's presentation, besides being easier, is definitely more elegant. As an alternative, you could get one really gorgeous roll of elegant brown paper wrapping paper and use that instead.

For an in-between, you can wrap your goods in brown paper, then angle some more paper squares to make points and bind them with raffia around the waist of the item. The points can be decorated with drawings or cutouts, flowers, ornaments, pen, paint, glitter.

Clear cellophane also works. The gift wrap kind. Be really generous with your cuts, angle a couple of lengths and bring together loosely. Tie with a big bow or twists of colored cellophane.

Use stiff cardboard (or plywood skin) covered with waxed paper or parchment paper under your baked goods if you don't have baker's boards. Don't use plastic wrap unless your baking has cooled for at least a day or you'll trap moisture. Wrap in paper or cloth instead.

Another nice way to wrap, btw, is just to fold new (or, better, new that has been washed once) pretty tea towels around the items. Pin in place with decorative pins or scarf clips or even just discrete safety pins (try to keep them from looking like diapers!). Gathering isn't such a good idea with cloth because the weight could disturb the goods.

There is a company called WrapSacks that makes cotton drawstring bags for wrapping. (Or if you're sewing inclined, you could make some yourself.)

If you want goofy, there are limitless ways you could go. You could wrap the items in funny T-shirts, for instance. Or use a little felt and glue to dress them up as sheep. Or Easter bunnies.

You could garage sale/thrift shop source some cookie jars, bread boxes, jam pots, baskets, etc., and put each item in its appropriate container, in its jar or bag or whatever basic covering you're planning.

You could make baskets out of window screening and ribbon, and hang little ornaments and even solar lights from them.

Whatever you choose, have fun. I know that your loved ones will enjoy your goodies.

Just my thought--if in the past, when people came to your home if they did not bring gifts or did so occasionally etc, I would not start anything. I think it is nice, BUT, if you want to do so, keep the gifts simple and inexpensive. My DD does gifts in a jar--that is a simple cookie/cake receive, all the ingredients in a jar with the recipe attached. Instead of gifts for each person, maybe a family gift such as a gift card to a favorite eatery, or a invitation for a later fun time, especially if you have events in your area that you know your relatives would like to see. Personally, I have hosted holiday meals for quite a large group of my and his families and each one of my relatives brought part of the meal which was there specialty--like my Aunts candied sweet potatoes which to this day I really miss. Another time my BIL with our permission brought 6 Airman from his base who were away from families and along with other friends and family we had a ball Lost of good memories!
