There are no crochet hooks needed.
I love how creative this is and some may have these materials already laying around at their house.
This woolen flower can be attached to any crafts or decorations you have.

I would attach this to a pocket bag or backpack for my little cousin or niece.
you’re free to even attach this woolen flower to a sweater too.
Then, wrap it around 5 times and make a knot in the middle.

Grab your second color and start at the slit under the first one at 4.5cm long.
Continue to wrap around the comb 4 times.
Second, take the yarn off of the hair comb.

Insert a needle and yarn through the holes and sew them together until it becomes one whole flower petal.
Repeat this until you get 6 flower petals.
In the end, I love how she added pearl beads to the end of the flower petals.
It gave a nice pop and touch to the flowers.
There are many tutorials out there that use everyday materials as a hack.
Its super convenient and inexpensive which saves a lot of time.
