After the box bag, now it is fabric tray.
It was not tough at all and it is the most simplest sewing I have ever done.( Well my doings are very few)
But again, it is not perfect because the fabric I chose was saree excess,( which was for the blouse and not required) so it was slipping.
Well, it is now used as a tray to hold all my yarn/wool/crochet threads.
Tutorial is here.
