In the beginning, you practiced the chain. Then a simple change has to be done in practice.
This is the pattern, anyone should practice as the first step of a pattern. Actually, you can't attach this for decorating purposes, but only to practice.
When you practice and practice with this type of work, you can easily control the fine movements of your fingers for crocheting. Crocheting is also work needed the fine movements of your fingers like writing. "practice makes perfect"
Do more practice and achieve your goals. Here, there are only two stitches used, chain stitch and double crochet stitch. So, easy to practice.

2. Then make 2 chains and make a double crochet into the loop of 7 chains.
3. Make 7 chains and turn over the work and make a dc into the space of 2 chains.
4. 2 chains and make a double crochet into the chain two space.
