The happy frog rattles, they cannot jump but croak loudly. With the tongue outside the mouth the frog can catch the flies quickly and easy. It is an ideal toy for the little ones; makes sound when they shake it and great to feel with the different structures of wood and wool.
The frog is placed on top of a wooden ring and inside the head a rattle is placed. With basic shapes of spheres the characteristics of the frog are visible. The finished result is 13 cm in height and 7 cm in width. The pattern is easy to crochet, you only have to know how to crochet the following stitches: chains and single crochet stitches. You need the following materials to recreate the same result as in the pictures. All the materials are linked to Pipoos, a Dutch shop, where you can buy all kind of craft materials.
My design process of the frog rattle shows that you cannot create the perfect frog in one go. I had to do different iterations to develop the frog and how it was placed on top of the wooden ring. It reminded me what I teach my students for product development: always start prototyping from the beginning since you cannot create the perfect design in one go, you have to create different iterations to optimize your design.
