Member and Joint
Construction

 

Member Construction

1. Place several small pieces of tape (2 cm) along the edge of the table or have a glue stick ready.
2. Roll a piece of paper into a tube with a diameter roughly the size of a quarter.
3. Carefully place the tube on the table top making sure the tube doesn’t unravel.
4. With both hands flat and palms facing down, position the tube along the middle of your fingers.
5. Roll the tube away from yourself while applying a gentle downward force onto the tube. The force applied should elongate the circular shape of the tube but not crush or crease the tube.
6. Reposition the tube and your hands once the tube has rolled to the bottom of your palms.
7. Repeat until the tube has tightened up to the size of a drinking straw. Gradually increase the force applied to the tube as it's diameters decreases.
8. Secure the tube/member with either tape or glue.

 

Joint Construction

Butt Members
1. Cut a piece of paper in half lengthwise.
2. Place several s
mall pieces of tape (2 cm) along the edge of the table or have a glue stick ready.
3. Cut a member in half.
4. Measure and place a mark 6 cm from the UNCUT ends.
5. Butt the uncut ends together. Center the cut piece of paper between the marks and wrap the piece of paper around the members lengthwise.
6. Repeat member construction steps 4 through 7.
7. Repeat until the paper is tightly wrapped around the butted members.
8. Secure the wrapped paper with either tape or glue.

Slip Tube
1. Cut a piece of paper in half lengthwise.
2. Place several small pieces of tape (2 cm) along the edge of the table or have a glue stick ready.
3. Measure and place a mark 6 cm from one end of a member.
4. Center the cut piece of paper along the marked member and wrap the piece of paper around the tube lengthwise.
5. Repeat member construction steps 4 through 7.
6. Repeat until the paper is tightly wrapped around the member.
7. Secure the wrapped paper with either tape or glue.
8. Slide the newly wrapped tube towards the end with the mark. Continue sliding the tube until the mark has passed completely beneath the tube and appears on the other side.
9. Approximately 5 cm of the newly wrapped tube should extend beyond the end of the member.
10. Carefully flatten the extending end making sure not to damage to member beneath the 6 cm of overlap.
