My 4 1/2 year old is starting quilting this fall. she has a nice selection of scraps all sorted out and ready to go. we plan to make a string quilt. luckily, my viking has speed control so i have her on the lowest speed. i put the foot pedal up on a stool for her to reach. i'll do any cutting for now. she can probably help press things if i lower the iron board way down for her. just be creative and let the child show you how much they can handle.
side note - Jane, you are amazing. great ideas! 4 at a time that qualifies you for saint hood!
