Cut a fabric and fold it into half. If you can cut and fold and make a perfect square, that's better. Sew an L shape and leave a corner to be opened. Or if you're joining 2 pieces of cloth, then sew 3 sides and leave one side opened.
Flip the fabric outwards. (flip it inside out)
You can either sew half of the opening first then fill it up with seeds , or fill them up an then sew up the opening.
This reminds me of my first ever project that I have sold. I used to make five stones and sell them for rm1 for a set or 30cents for single five stones when I was in standard 1. Haha yeah I keep selling and selling until my grandma find out that I have been using her rice to fill the five stones up. *lol* after that, I started making other things to sell.
****important notice******
Saga seeds are highly poisonous if its biten/opened. Please ensure kids are old enough to understand and won't put saga seeds into the mouth.
