Homemade sun-dried raisins

Spring has come. There have been a few days of unusual warmth and sunshine. So I decided to try sun-drying some grapes. I take them out in the morning, to be dried under the sun, covered by a thin layer of cheese cloth. In the evening, they come back indoor. If I happen to have used the oven. I'd allow the oven to cool down to just below 150F, and then leave the drying grapes in the oven for 2 hours or so. Then I leave them on the counter overnight.

They taste really good as raisins after 10 days. In fact, I think they taste better than the commercial ones.
