Rosalie is a great hexagon pattern, well written, fun and easy to make.
I used the July Alchemy fabric pack for the main fabric choices and used some of the 10 recommended fabrics for the other choices. It uses a minimum of 12-14 fabrics plus the background. For the background and binding in the same fabric, I used Carolyn Friedlander's "Architextures" collection in a light neutral color.
There are two hexagon sizes in the pattern. I chose the smaller hexagon and used template plastic for creating my template. I traced around the template with a lead pencil and cut out the shapes. There is also a template for the connecting triangles. Everything is easily explained in the pattern. Just follow the diagrams for the placement of the hexagons and triangles in the body of the quilt and a different arrangement on the end of the rows.
I put my hexagon shapes on my design wall and moved them around until I was pleased with the balance of color and pattern. The hexagons lend themselves to fussy cutting an area of design since they are large enough to allow each fabric to shine. The neutral triangles in-between each hexagon give a needed contrast to each hexagon.
If you are making a quilt, instead of a smaller project, you will need a 1/2 yard total of the 6 patterned fabrics in the fabric pack and FQ's of the other 6-8 choices.
I have no doubt you will enjoy making this hexagon pattern!
