So, I had a lot of fun with the 1.5" squares of the stitch samples. They went really fairly "fast", so I decided to challenge myself with a little composition. I figured it would be good to test these stitches out in non-square shapes. It was good that I thought to practice this, and Chloe, thank you for your suggestions on what to practice too!
I decided to use my design from my RSN Certificate Goldwork as I liked the design and it had some good solid areas to work with. I have done all the leaves in cottons (mixes of solid DMC's and variegated Valdani embroidery floss). On 3 of the leaves I used the same stitch for the whole leaf and just focused on shading with the stranded cottons. For the other 2 leaves, I attempted to transition from one stitch to another.
Further plans: Blossoms will be white and maybe a wee bit of pink or gray for shading in cottons. I was planning on doing the background in wool but not certain what color yet. I thought the shine of the cotton on the lily of the valley would be nice contrast with the wool background.
