I have a big pet peeve. I hate when someone sits a glass or mug on my tables. It stains the tables.
That is why I have lots of coasters.
I make my own crochet coasters using 100% cotton. Cotton is the best fiber to use to make coasters. It is much more absorbent than acrylic yarn.
Take a look at these!!! I make them different colors to match the different holidays.
These ones are star shaped in red/white/blue. Perfect for this 4th of July.
They are available on my etsy shop.
I also have these Christmas themed crochet coasters.
