Weaving
Lesson 2 of 4
22 min
Try weaving with loose threads on a table and they slide everywhere. A loom solves this. Every loom, from a notched piece of card to the large treadle looms used in textile workshops, does two jobs: it holds the warp tight, and it keeps the warp threads evenly spaced. If you build the loom well, weaving becomes easy; if the warp is slack or uneven, no amount of care will make the weaving straight. Think of the inanga: its single long string is laced back and forth across the wooden trough, evenly spaced and tight. A loom's warp is set up in much the same way.
You need: a piece of stiff card about 20 cm × 25 cm (the back of an exercise book or a box), a ruler, a pencil, scissors, tape and cotton string.
You need: four straight, dry sticks (bamboo or eucalyptus), two about 40 cm long and two about 30 cm long, sisal twine, small nails and a hammer (ask your teacher for help), and cotton string.
Byiringiro's stick frame measures 30 cm by 40 cm on the inside. He measures the two diagonals, corner to corner: one is 52 cm, the other is 48 cm. When all four corners are square, the two diagonals are equal; for a 30 cm by 40 cm rectangle they are both 50 cm. So his frame leans. He pushes gently on the two corners at the ends of the long diagonal until both diagonals read 50 cm, then tightens the lashing.
Uwase wants a weaving 12 cm wide with warps 1 cm apart. Many students answer 12, but count the gaps: 12 cm holds 12 gaps of 1 cm, and each gap needs a warp on both sides. The first warp is at 0 cm and the last at 12 cm, so she needs 13 warp threads and 13 notches at the top and 13 at the bottom. This is the same rule you use for fence posts.
This tapestry is still on its frame loom. At the top and bottom you can see the bare cream warp threads stretched between the bars, evenly spaced like the strings of an inanga. In the woven part the weft has been pressed down so closely that it hides the warp completely.

Tip
Tight as a drum, even as a comb. Before you weave a single row, pluck every warp: they should all feel equally firm. Fix a slack warp now, because you cannot fix it later. For any spacing question, remember the fence-post rule: warps = gaps + 1.
Name the two jobs that every loom does.
Solution: it holds the warp tight, and it keeps the warp threads evenly spaced.
A cardboard loom has notches every 1 cm across a width of 18 cm, with a notch at each end. How many warp threads will it hold?
Solution: 18 gaps of 1 cm need 18 + 1 = 19 warp threads.
A stick frame is meant to be a rectangle. Its diagonals measure 62 cm and 58 cm. What should the builder do?
Solution: the diagonals are unequal, so the corners are not square. Push the corners at the ends of the longer diagonal towards each other until both diagonals are equal (60 cm each), then tighten the lashings.
Keza wants to weave with thick strips of kitenge. Should she space the warps 0.5 cm or 1 cm apart? Why?
Solution: 1 cm. Thick weft needs room to pass over and under; with warps too close together, the strips would bunch up and the weaving would bulge.
