Glue each yellow strip to each dark yellow strip to make one long strip. Repeat for a total of almost 50 strips.
Fringe each strip using scissors or a mechanical tool. Roll it over the quilling needle, secure with glue and after that fluff the fringe.
Also, make white and orange flowers like in the below picture.

First stick the yellow flowers. Spread a little glue onto the back of the fringed flowers.
Using a toothpick or a small paintbrush or directly from the glue tube. Place each flower on the edge of heart background before drying the glue.

Second continue with the orange flowers. Place flowers following the heart shape.

In last, fill the heart shape with white flowers. Stick the white fringed flowers in the middle of the shape. You have finished!
