Most challenging of all the 18 squares bec. of 3-d effect but I'm so interested in perfecting this. 

Step-by-step tutorial on motif square. I was looking for a square to crochet for a project I have in mind but I found these patterns (18 squares) in Pinterest and I couldn't choose or couldn't tell which one is the best. So to help me decide, I crocheted them all to see how they will all actually look when crocheted. And I decided to call them Crochet Square Challenge. This will be a compilation for myself but I would like to share them with everyone too.
