Make or use a batch homemade modeling playdough [see yesterday's post for one possible recipe].
[Make it big enough for the string or lace you will be using later.]
Bake at 225 degrees a few hours until hard [or leave out overnight to dry thoroughly].
For easy bead-stringing without a needle, dip the end of a string in glue and shape the end into a point. Hanging with the point down, let it dry thoroughly. If you have made the hole in each bead wide enough, a shoelace will also work.
Note: For younger children be very careful to make the beads large enough to avoid a choking hazard.
