Depending on their ages, you can make tote bags for their doll clothes or hot wheels cars, pillowcases for each holiday. Mine especially loved the glow in the dark fabric for Halloween. I embroidered on the pillowcase cuffs for Christmas - "Dear Santa, I've been SOOOOO good!" Personalized placemats. Winter scarves. Nightgowns with flowers embroidered on them. If they are little enough, look up pillowcase dresses. And, of course, you can make them quilts with embroidery in each block.
