Using cotton yarn in 10 different colors, I created a piece measuring approximately 23 x 18 cm with diamond shape patterns.
As you can see from the close-up view below, I made 5 rows of single crochet (sc) with each color. For every first row of color change, repeat spike stitch pattern.
I made a inner lining of the same measurement as the front piece using the color beige...
and a separate pocket piece, measuring approximately 23 x 10 cm.
For this piece, I made 2 rows of sc with each color and spike stitch pattern upon color change.
Here is the result.
Here comes the part where I had to sew individual pocket slots. As I wanted to create a seamless look for my pocket piece, therefore, I had to sew through the back of pocket piece together with the inner lining.
I also inserted two pieces of cardboard measuring 10 x 17 cm each in between the front and back pieces to give it a 'backbone'.
I crocheted a flower to serve as a 'button' for my case…
Here it is, my home-made crochet hook case.
