These sewing cards are great for children learning how to write. They build fine motor skills, teach or review how the letter is made and teaching beginning sewing skills. Take a piece of cardboard or cardstock. We used cardstock, but it does bend some. Draw a letter, number or shape (whatever your child is working on) with a thick dark marker. Punch or poke holes at regular intervals around what you have drawn. Have your child use a plastic canvas needle or other large blunt needle to sew yarn around the letter, following the holes you have made.
