My niece makes some nice pottery. In one corner of a basement room of our home is a large earthy pot she made. It's too big to place on a table, but it's perfect for a corner. When I come home from work, or when my husband comes home from work, and anytime we have extra change, we empty it into the pot. That "extra" change paid for a recent Saturday trip to Dutch Wonderland.
My husband took my son to the park while I was at work. (I know, not fair, right?)
My son had an extra ticket that his daycare shared with us. The change in the pottery jar paid for my husband's ticket. We only started adding the money earlier this year, but it adds up -- $51 worth this time. So, don't count out the extra change you might have.
Nate, my husband, saves all his change. I think he must have $300 to $400 dollars in canning jars.
