Texture issues around writing materials have often been mentioned on this forum. DD8 is dyslexic but no (known!) fine motor issues, and loves the whiteboard (alternate choice: fountain pen). Her teacher (bless her!) just lets DD go to town on the whiteboard and when she's done, snaps a photo to add to DD's folder. The teacher obviously saw enough difference in output quantity/ quality to encourage this. DD also has visual processing issues, and I wonder if between the two LDs, in addition to texture she may also just find it easier to write on a physically larger scale (the bigger the font the better for reading).

For the record, her clothing-sensitive father will use exactly one kind of pen, and woe betide us if he runs out of them.
