The picture does not do this project justice.
Print the page on construction paper. Lay the page on a rotary cutting
mat that is used with quilting. Take a hallow punch and hammer. Use the punch and hammer to punch out the circles. Have the children lace yarn
into a plastic needle and "sew" around the patterns.
There is an easy version that has a only a heart and a harder version
as is shown in the photo.
Here is a set of punches used for this project.
