And now ... the rest of the finishing instructions ...
Measure the top of the pincushion and cut squares of quilt patting about the same size or a little smaller.
Place the squares in the pincushion and mush them down until they just fit. You want them to fit tightly, but not too tight.
Fold in opposite sides and lace together.
Be careful of the tension. If you pull too tight or not tight enough you will distort the box shape.
Repeat with the other two sides making sure that the edges are tucked in. If you want to add a bead or button to the center, now is the time. It helps to have a really long needle. Go up from the bottom and come out of the top center. Pick up the bead or button and go back down through the center and out the bottom. Tie the ends together tightly and cut off. I finish with a drop of nail polish. (Somehow I missed getting a picture of this step)
Next, cut a felt square just smaller than the pincushion bottom and pin in place. I've used a wool blend felt.
Whip stitch the felt in place using a thread that matches the felt. I double stitch each corner. Remove any basting thread as you go.
Turn over, insert needles and pins and you are done!
