Lines and Shapes Designs

This is 4 designs that I made for class using shapes and lines to create different abstract designs

In this project we were ask to do come up with designs only using lines and shapes.We could use repetition but no color and for the shapes only geometric shapes were allow.I made this designs in illustrator while I was still a beginner,which made it really difficult for me to do them.I wanted to make my designs with shapes to be interesting but simple, thats why I didn't use a lot of shapes in my designs.I wanted to play with the white space and black space which is why in some of the shapes the white lines go over to the white background because I wwanted it to look as if the white was from the background.For the line designs I wanted to use repetition and I wanted to play with both straight lines and curved lines.
