I also get a batch of presents I don't want every year. I usually end up returning them, but that may not be an option for you. Maybe you could send them back to the givers and say kindly that you appreciate them, but they just didn't work out for one reason or another. If you keep doing this, they will eventually stop sending them, hopefully.
I keep reminding myself that people enjoy giving gifts, so I shouldn't deprive them of the joy of giving.
By the way, I too love homemade, creative type gifts and usually try to give them. No one seems to get the hint in reverse, however... Maybe they dread my homemade, creative gifts each year!
