You can certainly choose a CMYK or HSL dialog in the fill and stroke and all colour pickers, but it converts all colors to 8 digit hex as you willl see in the bottom of the picker. Since RGB and CMYK spaces are both device-dependent spaces, there is no simple or general conversion formula that converts between them.
Fold and press the sides. Working on either the left or the right side of the fabric, fold the fabric over 1.5 inches and pin. Do this the entire length of the fabric and then use your iron to press in the crease. Now fold that edge over another 1.5 inches, pin and press. Repeat that process on the other side of the fabric.
Crease the resulting fold and cut along this crease to make a triangle. The crease will be at a 45-degree angle to the edges of the fabric, which is the true bias. Weâll be using this angle to mark the rest of the bias strip edges, so cut a nice, straight line.
