in the same manner as before, turning
seven straws each time. As the diameter of the mat increases, the
less often is it necessary to add. But be sure to add enough to keep
the weaving close and the mat perfectly flat.

Step 9 shows how to close the edge of the mat by turning back the
straws on each other. It also gives a very pretty "woven in" design
for a border, which can easily be followed from the plate.

Square Center.

Steps for commencing a circular mat with a square beginning are
illustrated in Plate XXI. The additions at the corner are made in
the same manner as explained in the radiating center, except that
each is for a fourth of a circle instead of a complete circle.

Decorations for Round Mats.

Decorations are often employed in round mats. (See Plates XXII and
XXIII.) The most usual are concentric or radiating colored bands of
either simple or sawali weaves.

Hexagonal Weave.

Step 1. In Plate XXIV, place straws 1 and 2 parallel; then put 3
under 2 and over 1; put 4 under 1 and over 2.

Step 2. Put 5 over 1 and 4 and under 2 and 3; put 6 under 1 and 4
and over 2 and 3.

Step 3. Put a over 5 and 6 and under 1 and 2. Put b over 1, 2 and a,
and under 3 and 4. Put c under a, over 4, 3, b, and under 6, 5.

Step 4. Put d under b, over 6, 5, c, and under 2, 1, e. Put e under
c, over 2, 1, d, under 3, 4, and over a. Put f under d, over 3, 4,
e, under 5, 6, a, and over b.

Step 5 is made open so as to show the triple over and under
weave. Further weaving is merely a repetition of this process, as
shown in step 6.

Step 7 shows the turning of the straws on finishing the edge of
the mat.

Step 8. Many designs can be made by inserting colored straws into
the natural weave. Step 8 illustrates three of these embroidered
designs--the star, the bar, and the diamond.

Embroidered Mats.

The embroidering of mats is easily done and the method is shown in
Plate XXVI. Mats in over and under weave, of solid color (either
natural or dyed), are used, and the embroidery is done with colored
straws. Plate XXVII illustrates an embroidered color panel. Floral,
geometrical, and conventionalized designs are discussed under the
headings "Samar mats" and "Special designs."

MAT MATERIALS.

Many Philippine mat materials have been described in a former
publication on hats. [6] Only additional and new information is
written here and such data from Bulletin 33 as are necessary to make
