You will need:
Pattern pieces (see Step 1)
Three colours of felt (your choice of colours)
A small button
A metal hair clip
Needle and thread
Save the pattern image below to your computer by right clicking on it and selecting 'save as'. Print the pattern - I recommend that the largest flower is about 3.5cm across.
Using the pattern pieces, cut one flower in each colour.
Secure your threat in the middle of the largest flower piece (for info on how to do this, see here). This should be on the topside, which is the side facing up when the piece is complete.
Place the hair clip on the bottom side of the largest flower, ensuring that the slots are central. This central placement of the slots in the clip is important, as it needs to allow for the button to be sewn on through them in the next step. Secure the clip in place with a few stitches.
After a few stitches, your hairpiece will look something like this on the bottom and top:
Position the two other flower pieces on top of the largest one. I like to do this so that the petals are offset, but this is personal preference.
These are then secured in place by sewing the button on top, with the thread being passed through the slots of the hairclip. Sew through the button holes several times, as this will safely hold the whole hairpiece together.
Finally, pass the thread through to the topside of the largest flower and fasten off with a couple of backstitches. Ensure that these stitches are hidden below the petals of the flower above to give a neat finish.
