Select a packet of seeds for each greeting card. Use the glue to attach the packet to the front of the card. Don't use a hot glue gun for this, because the heat can damage the seeds inside -- use either a glue stick or regular craft glue.
Use your markers or other craft supplies to write a Spring message inside. You can use something like this if you like:
Wishing you blooms and abundance at Ostara!
or
Roses are red, violets are blue,I picked out these seeds, just for you!
Ostara blessings to you and yours.
Give the cards to friends for the Ostara season.
