Watercolour Technique with Over the Moon

Hello lovelies, Happy Mother's Day to all you beautiful ladies! I hope you had a wonderful day and got a little bit spoilt because we so deserve it!

I have just finished my third Cow Card and I am feeling a little 'Over the Moon' about them!! To create the background is not a new thing, but I got a few queries on how I actually did it and thought maybe some of you might like to know too?
