Memorial Day kicks off the unofficial beginning of summer, and the holiday weekend is often celebrated with a barbecue or picnic (maybe with some delicious berry kabob cupcakes). Need an outdoor craft to keep the kids busy while food is being prepared? Paint some river rocks that can later be used as Memorial Day Tablecloth Weights to keep the wind from ruining your perfect picnic.
Cover your work area with newspaper.
Paint rocks with acrylic paint using whatever designs you choose.
Allow paint to dry. Then, spray each rock with clear acrylic spray to seal in the paint.

Use your scissors to cut the elastic on the ironing board cover fasteners to fit to the back of your painted rocks.

Glue each clip to a rock using your strong glue that can bond non-porous materials, such as E6000.
Allow glue to dry (it may take several hours for the tablecloth weights to fully dry and you may have to wait to use them at your next picnic).
To use, clip each Memorial Day Tablecloth Weight to each corner of your picnic tablecloth to keep it from flying away.
