I am a PPing junky....and would LOVE to join as I also LOVE mini's...but in PPing, especially this small, you really need to leave the paper on to keep it all secure! I used to own a miniature paper piecing group and one time we swapped with maker's choice and it was a nightmare! The blocks don't travel well and they easily pull apart when trying to put them together into anything. Even with stay stitching the outer edge. They really need to have the paper left on!
another site for free patterns is paperpanache, but they are pretty complicated!
