Primitive Halloween BOO Black Cat Jack O Lantern and Ghost Mini Wooden Block Set of 3. I've been having fun making up these single mini wooden blocks. If you decorate with those tiered trays that are so popular, then this block set is perfect for that or anywhere in your home for a fun Halloween decor item! The block face has been painted khaki tan with a black cat as the B, a jack o lantern for an O and a ghost as the other O. The block is all stained. The block is 2" thick and measures 3 1/2" x 3 1/2" for the Jack O lantern and Ghost blocks and 5" tall for the B (cat) block. Hand painted, designed and signed by Heidi.
