You can use feed bags for the water-proof liners. You can also use them to make reusable grocery bags and eliminate the plastic bags you get form the store. You can sell those also. I've seen on the "Everything Else" thread where somebody is making purses out of them. I saw an article in one of the poultry magazines on how to make them. I started seeing them everywhere after that. They really would be handy to have and if you sold them for cheap they would sell.
As far as the eggs, you can paint poinsettas, santa's, and wrap a ribbon around them and add a bow and you've got a presant to hang form the tree. You can use colored construction paper and cut out a beak, comb and waddles. glue some wiggly eyes on and you've got a chicken. Glue on a few feathers. You have chickens, you have feathers around. When mine moult I gather the best feathers for future use. You can also sell the feathers if you collect enough. If you have rabbits you can sell the poo. People around here use it in worm beds.
A few years ago I went around to all the yard sales I could find and bought every terra cotta flower pot I could find. And painted them, added flowers and other decorations. I made 2 sets that I painted red and painted black dots using a piece of cardboard that had a perfect circle in it as a template. I then glued those puffy balls thingy's ? on the outerside of the top edge and glued wiggly eyes on them. I used a black pipe cleaner to make antennas and glued them in place. They looked like lady bugs. I also did some with black and yellow stripes use a black puffy thingy for the head, cut a small yellow strip to put on the forhead of the black poofy head and added wiggly eyes and black antenna. I had bumble bees. They where so cute. And took very little to make. You don't want to paint the inside of the pots though. Just clean them up real good and let dry before you paint them. I also make wind spinners out of plastic canvas. I just love them and still make them. They are time consuming and don't sell for alot but I make mine for myself and sometimes somebody will want some. I make all sizes and use different color canvas and beads and use that spiderwire fishing line to string it all together. I use swivels from the tackle box and round key chains to hang them from. They are time consuming and compared to the time that is in them, it's not worth what you may be able to get out of them but they're pretty to have in your yard. Wooden ones would sell at a higher price.
Just about anything you find at a yard sale or a good will can be made into something very nice to sell or to use as gifts. I know I would rather have something somebody made for me than something store bought. It means more.
You can buy up a bunch of old necklaces at yard sales and thrift shops that are made with beads and break them down and use the beads to decorate your purses with. If somebody you know is wanting to clean out a room or get rid of things ask if you can have it. Never know what you will find you can use. I got a bunch of old wreaths and took all the old stuff off of them and put new flowers and decorations on them. You can decorate a wreath for every holiday. A dab of hot glue on each piece to make it stay and your done. Those are fast to make and cheap. You can decorate old cigar boxes with material or beads or both and have a treasure box for somebody to keep their keepsakes in. If somebody has chickens you can make a pretty apron with wing guards on it for their favorite chicken or a decorated frame.
You can save alot of money by making most of the gifts yourself out of what ever you find. Then using the money you made off of the things you sold for the harder to gift people. (we all have them)
I had an order for a chicken apron with a wing guard and with all the storms I was nothing but nerves so I concentrated on making this item and by the tme I finished it, it was sooo cute I didn't want to let it go. But I did and the person that bought it was so pleased with it. I decided to make some more like it. I used material I already have. I cut pieces out of a piece of felt to resemble flowers and some as dots and hand sewen them on the wing guard and the apron. The apron is versitile becauses I had sewn snaps under the wing guard so it could be removed when not used and it had a saying under it.
Old wicker baskets can be converted to useful baskets with a material lining and beaded along the seam at the top or flowers weaved into the wicker at the top add some pine cones or decorated foam eggs. The ideas are endless.
