Tried the cross stitch generator on one of the drawings from a comic about online safety for girls I had done for Akshara Foundation.

Later I developed some character sheets on a graph paper

Once I felt confident, I tried out the Marmoset Hexels pixel art software. This can also be done with a custom brush on any drawing app, but the workflow seemed more intuitive with this software (though these were on the free version):

This project was for a Class 8 facilitator manual teaching STEM to Girls for IBM

I still like the handmade quality of drawings on graph paper
