Summarize:

The colors you use can change the outcome of your project. Quilling comes in many different colors, so you have lots of options. Try choosing a few different types of quilling in coordinating colors.  For example, you could choose black and white quilling, pink and green, or yellow and blue. Opt for colors that look good to you and that will work for your design. Consider what you want your design to look like as well. For example, if you are making heart shapes, then opt for pinks and reds. If you are making a cone for a Christmas tree, then use green quilling. You will need to use a quilling needle to coil your quilling. Wrap the end of the quilling around the quilling needle and then begin to turn the needle to wrap the quilling around it. Keep turning the needle and coiling the quilling until you reach the end.  To make your coils larger, use multiple strips of quilling. Just glue the ends of the strips together before coiling them. For flat quilling designs, you can coil the quilling tightly or leave it loose to create different designs. You can shape the flat coils into different shapes by pressing on the edges. You can leave the quilling in a circle, squeeze the sides to make it into an oval, or press on all four sides to shape it into a square.  You can make a heart shaped quilling design by making two coils, loosening them slightly, and then pinching them on the ends to make a teardrop design. Then, glue the two pieces together along the flat edges to create a heart shape.  You could even try using a mold to help you shape your quilling. For example, if you have a small star shaped cookie cutter, then you could place a loose spiral into the mold and push out towards the edges of the mold to form the shape into a star.
Choose your colors. Coil the quilling. Shape the designs.
