C is for Celtic and CO2

This month I am participating in the A to Z Challenge.  Each day of April, except Sundays, represents a different letter of the alphabet and I will be posting Zentangle art using patterns that start with the letter of the day.  I have been wanting to learn more tanglepatterns and I am using this challenge as incentive.  If you are interested in joining the challenge or checking out some other blogs, visit this link.

This is my version of Celtic and CO2.

My celtic is a little wonky, but it was the first time I have ever tried this pattern.
