I have a free template here for this matching heart activity to use on a felt board.  This listing is for the white numbers and hearts to iron on to your felt pieces.  Felt hearts are not included.

Iron on vinyl will last and looks so much nicer than the alternatives.  It is easy to apply and instructions will be included!

It will be mailed in a regular envelope with a stamp to save you money, so there won't be tracking.  But you will be notified when your order ships.
