You can join in this Hexalong at any time and use the templates I am using or just do your own hexagons. The starter post for the HAL is here. Share anything you make in the Lily's Quilts Flickr Group.

Here are some suggestions and possibilities drawn out on paper.
An example is in this block. I English paper pieced this in exactly the same way as all the other blocks but snipped into the internal corners in the six outside segments.
