I made this based on "100 Montessori Materials to Develop Children's Talents." I've changed the colors of the left and right strings to make it easier to see where each string goes. Please demonstrate how to tie the knot slowly. I've included instructions for tying a bow (A4 size). Please, parents (or caregivers), refer to these instructions and demonstrate slowly. This is handmade by an amateur, so there may be some imperfections such as warping or crooked stitching. Please refrain from purchasing if you are looking for perfection. ◯ Size: Height 15cm, Width 21cm
