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.
The second fold folds one part of that line onto the other. If an angle is folded through its vertex so that one side of the angle lies directly on the other, the fold bisects the angle. The straight line of the original crease forms a straight angle (180Â°) around any point on it.
