love the journal idea. some day she can look back & see"spent the sewing with Nanna". give her a stash of pre-cut blocks (5")or so. ask your friends to wrap up some pre-cut blocks also to get surprise & variety. she can learn 4-patch, then 9-patch, etc. good marker for her seams.(blue tape, etc.)
a micro cart could make her ironing surface on the top,under neath could be her own place for her stuff.then it could wheel out of the way when she is not there. foot pedal on a big block of wood so her little feet can easily reach it.
