Weaving Mats

You may have seen woven baskets
of different kinds. If you look closely,
you will notice different weaving
patterns on each basket.
We will try weaving some mats with
paper strips.
1. Let us make paper mats.
You will need — A coloured paper (30 cm long
and 20 cm wide) and eight paper strips of
two different colours (3 cm wide and longer
than 20 cm).
(a) Take a coloured paper 30 cm long and
20 cm wide.
(b) Fold the coloured paper in half along the
longer side.
(c) Draw vertical lines at equal distances from the closed
end and cut slits leaving a gap of 3 cm at the top.
(d) Carefully unfold the paper. There will be no cuts in the
paper at the top and the bottom.
(e) Now cut 8 paper strips of 3 cm width in 2 colours and
of length slightly longer than 20 cm.
(f) Take one colour strip and weave it across the slits going
1 under and 1 over, and again 1 under and 1 over.
Repeat it for the first row.
(g) Take one more strip of another colour and weave it
across the slits going 1 over and 1 under, and again
1 over and 1 under. Repeat it for the second row.
(h) Weave all the strips in the same alternating pattern.
Neatly fold any extra strip ends behind the mat.
Your mat is ready!
We can describe the pattern of the above weave as follows.
Row 1 — 1 under, 1 over, 1 under, 1 over, … (repeat)
Row 2 — 1 over, 1 under, 1 over, 1 under, … (repeat)
