I have the heart yo-yo maker by Clover (and all of the others, to). It only makes one size of hearts ,so far. they are about 1& 1/2" by 1& 1/2 ''. It makes making them so much faster. I ,too just asked my sister yesterday the same question as you.How would you make larger ones with out the Clover forms. I make them and sew pin backs on the back and make fabric jewelry out of them.
