While at Pike Place Market there is a wonderful little quilt shop too. Think it is called Underground Quilts. At the market entrance of 1st Avenue and Pike Street, head South. It is about 1/4 block on right side.
The Chihuly Glass Museum is located below the Space Needle and worth the look.
I'd do a walk on ferry ride over a boat tour. You can drive to Ballard to walk into and view the locks in action.
