By way of explanation, I have a young (age 4) son with a developmental delay in his fine motor skills. He has a difficult time holding a pen and controlling his hand/wrist movements finely enough to create letters or pictures.
His cognitive skills are normal, so it's frustrating for him when he tries to write a word or draw a picture and his images just don't turn out like his preschool classmates' pictures do. As a result, he's been avoiding using a pen, brush or marker at all.
He'll sit next to me and dictate what he wants me to write or draw - which is an enjoyable thing to do together, but while it's certainly helping his spelling skills, it's not helping him develop his fine motor skills. I really want to encourage him to practice using a pen (or marker, brush etc.) while keeping it fun and rewarding.
One thing I tried recently, with some success, was making a sketch with watercolor pencils, then giving him a water brush so he could trace my lines (or just paint the entire thing, if he chose!) and end up with an image he was proud of.
Enough background...here's what I'm looking for!
I'd like to try sketching with a permanent fountain pen ink, then adding some watercolor pencil so when my son paints with his water brush, some of the image will remain unchanged. For example, I might write some words for him in permanent ink with my fp, then add some watercolor pencil so when he's finished the words are clearly legible, but also surrounded by a colorful watercolor-painted design.
My top priority is to find a black ink that will be unaffected when it's later painted over with water, but I'd certainly be interested in other colors, as well.
Thanks so much for any help you can provide!!
