Lots of ideas have floated around my head about the storage underneath my perfect ironing surface. And I didn't even wake up once during the night with ideas - guess it's was not an earth shattering decision!
I finally decided on cube/cubby hole storage. Some are closed in the back and others aren't.
The open ones are perfect for long things like freezer paper and appliqué mats.
I keep my water for ironing in Dasani bottles. It is tap water - I do NOT buy water for pressing!
