There aren't any Kids Workshops or Build and Grow Clinics this weekend, but if you have a daughter (or niece or granddaughter) that is a fan of Fancy Nancy, you can head to Michaels for Fancy Nancy: Design a Tiara & Storytime. (Imaginative fun for crafty little ladies. Free Make-It Take-It While Supplies Last Ages 3 and up)
Then, since that event runs until noon, while you are out, you can stop at Friendly's for a free Fribble. They are celebrating 76 years of patronage and the future. Limit one per person at participating locations. No purchase required. 12 oz Vanilla, Chocolate or Strawberry only. I'd call ahead, just in case your location is not a participating location.
