Crocheted round coasters

I made some round coasters . The yarn used is a cotton one. I was so addicted to it yesterday and was making a lot of them. It was so much fun.  The finished coasters look like they have tiny blue dots on them. I was thinking of adding some sequins to make some bling. Coasters are  just to protect the table surfaces and why they need to be shiny?
Anyway, it was bright in the afternoon and I was able to take some pictures of them. So I can add them to my blog here.
Also, Twisted stone Designs has send an email to create a teeny weenie avatar to put in her blog. I  made one from my picture collection. She knows a lot about adding avatars of others in a blog and hopefully, I will get some help to add other artisans in my blog too.

I tied 4 rounds using a crochet chord. It looks like this:
