Wavy outline - technical question

Im trying to fill in the gaps between the waves. im working in indesign, and im wondering if anyone knows if theres a way to do this? i tried by stroke options doing a gap color, but it fills in the inside and outside - while im looking to just fill in the inside.
Any help would be appreciated.
Thanks!

The only way that I was able to do it was to bring the wavy stroke into illustrator - fill it in with your desired color and then bring it back into indesign
If anyone else figures out a better way - please post!

I can think of a quicker way in indesign
maybe if you create outlines, then delete the inner lines it would work?

right acc to this it’s to be done in illustrator - How to Fix the Fill on Items with Wavy Strokes | CreativePro Network

Thanks Adina! It worked, and was actually really simple. :slight_smile:
