Thank you @mrscwin! 😘 I feel happy now that I am finally making use of those yarns now. I bought them when I was very new to crochet and was looking at the cheapest option. But as I found nicer yarns, I started neglecting these cheap yarns. And now, they are happily lying down behind the fish tank floor 😁 (I hope they are happy though they don't have a choice).
Oo yes, I am thinking of more rugs now. Maybe we can try sewing on some rubber bands under to give it some friction
