The Ballard Art Walk is this Saturday. That gives you a lot of great options.
While your in Ballard, check out Velouria, which features beautiful clothing, all made by independent designers including many from the Northwest and other beautifully designed gifts like the journal above. Lucca Great Finds is the perfect place to pick up a beautiful card among other things.
The U-District Farmers Market is also on Saturday. The perfect place to grab some locally made wine and cheese or how about kombucha, smoked salmon, kim-chee, truffles or honey for the foodie mom.
Melrose Market is great for flowers and gifts and meats and cheeses to make your mom a great meal.
Paper Delights in Wallingford is fun to browse through for the perfect card.
There's always the Seattle staple gift, Glassybaby. Pick out one with meaning like "gratitude"(above). Check out their Mother's Day suggestions. Not only is this an ever-growing small business started by a mom, they give 10% to great charities.
Nube Green on Capitol Hill is filled with wonderful finds, all sustainably made by artists all over the U.S. I think the "Call Your Mother" pillow (above) is hilarious.
