Hi, I am happy to know that I have many new friends of the same interest. Thanks to all of you.
@ Loretta: I just followed the instructions in the e book, they were easy to follow. @Elisabrat: I used sewing chalk to mark the diagonal lines even. @Sheila Elaine: Yes, to me, cutting through the fabric was the hardest effort. I did not have a rotary slash cutter available here, I used small fabric scissors. In my next experiment, I'll make the diagonal lines width smaller and use different cotton fabrics. Let's all give a try! :D
