Anaya's Procedure

1. Gather materials

2. Draw a straight line down the length of the straw. Make three marks (2 cm apart) on this line on four straws.

3. Use a star-shaped scrapbooking puncher to make the cut at each mark. One point of the star should be enough.

Bend the straw to test its flexibility.

4. For the thumb, make the first mark on the straw 2 cm from the top of the straw, then measure the next mark 3 cm from the first mark. Use the puncher to make the cuts.

5. Lay the fingers according to the length of your design and cut the bottom of the straws leaving enough straw length for the hand. Measure a piece of dental floss about 4 times the length of the straw and thread through the needle. Push the needle just above the first hole, guide it down the straw, and make a knot at the top.

6. Carefully punch four holes on the top of the box with the scissors and one on the side for the thumb. Push the fingers and thumb through each hole.

7. Thread the floss of one finger through the needle and have the needle go through the bottom of the box. Remove the needle and attach a washer to the end of the floss. Repeat for all strings.

8. Test each finger and use tape to support each straw.

9. Add a glove or handle.

10. Test it out, pick up stuff.
