I need to attach an appliqué to a granny square that will be apart of a blanket. Do you have a special way of hiding the yarn you used for attaching? Or is it normal just for it to show since it will be on the back? I hope that makes sense. Let me know if it doesn't.
The appliques can then be easily sewn on with a running stitch and yarn or maybe crossed stitches or even crocheted on with a single crochet around the edges or a tambour stitch. I would try the tambour stitch. The yarn used for attachment will stay at the back side of the work. Push the crochet hook through all thicknesses and pull up a loop. Extend the loop as far long on the top as is attractive then push the gook back through and pull up a loop from the back and through the loop just made. It appears to look like a crocheted daisy chain. Here is a link for the technique:
Hum.. I wonder how that would look all done. Thanks for the idea Marie! I'm going to look at all the appliqués and decide if they would look good that way.
