It's a process. If at first you don't like it, add more. But knowing when to stop is the tricky part. if you have to ask "does it need more?" the answer is usually "no.". Put it aside, wait until later or tomorrow and then you'll know.
On the other hand, sometimes you know right away.
Sometimes you just need to add a little bit to make it work. And making marks with a syringe always adds pizazz.
We're done printing. Now it's time to use the fabric to make quilts! Tune in tomorrow.
