Video Instructions Concertina Fan:

1. Damp the T-Shirt. Spread the T-Shirt evenly on your table and make sure that the seas are even as well as equal.
2. Mark with twine and a dressmaker’s pen from one corner to the other. Mark, the hold, and go in an arc shape. Make sure that the lines are continuous, longer and clearly visible. Go over the lines are the second time to make sure they are visible.
3. Pleat 1,5 cm folds from one edge to the other end (concertina). Use a plastic knife to measure evenness. This process takes about 30 min to ensure everything is even and neat. The blue line needs to be visible to make sure everything is neat. With a string, tie a knot in the middle over the marking using a quick-release knot.
4. With a ruler, measure and mark the next pleats (4, 8, 14, 20 cm and 6, 12, 18 cm, then again 4, 8, 14, 20 cm on the other side). You can choose the distance you like. Draw a line across and then pleat neatly.
5. Now all pleats are done. Count the number of pleats and decide on the colours you would like to use (for example, 4 colours and 16 pleats = 4 of each colour).
6. Get a baking tray with a wire rack on top so you can collect the dye.
7. Place the T-Shirt flat on top of the rack.
8. Now we are starting to dye the fabric. Make sure to use colours that go well together and don’t clash. For example, you can use blue, pastel lime, deep blue, green and use some purple for extra added effects. Turn the pleat over and repeat everything on the other side.
9. Leave everything outside in the sun and turn it in every 20 min.
10. Once it is starting to dry, gently untie all the ties very carefully. Open the T-Shirt up slowly ¼ at a time and leave to dry in the sun. Now you have to keep turning it more frequently every 5 min. Open from the middle outwards.
11.  Now you can open the shirt completely and lay it flat to dry. Don’t forget to keep turning it.
12. The item needs to be heat set once done to avoid the fading of the colours.
