hmm... interesting question. I just gave DIL a Cricut last Christmas (although she didn't bother to even figure it out despite having on her wish list--son did just it to make vinyl stickers for political signs)and I have a Silhouette original Cameo--but while it does have ink pens you can slip into the holder, I don't think it's permanent ink, at least on fabric. But I think I'll explore that some to see if any of the permanent fabric pens will fit into the holder.
