Thanks for all the input on color choice for the last round of this doily. It really helps to hear other opinions, and I did think about it a little differently after reading the comments.
My first thought was the lavender because it would probably blend in subtly, exactly as some said. But then I thought about the comment saying whatever color I chose would be the main color of the doily overall. Lavender didn't seem like a good choice then. Green was good too, but it seemed like it would be too dark.
I did really like how the yellow/peach thread matched the color in the Summer Trail, so after thinking about what the overall color might be, I went with that one. It matches very well, and doesn't stick out as dramatically as I thought it would. Finally done! It's good to turn that To-Do into a Ta-Da.
That said, I'm going back to making doilies in mostly ecru, cream or white, with just a little color accent. Who in the sam hell would use a doily this color? The thread is beautiful, the pattern is beautiful, but really, as a whole it is not appealing to me. I'm not sure why I thought this variegated thread was a good idea - I've always crocheted doilies in a cream, white or ecru, with possibly a hint of color using a solid thread. Is it just boring old me? I think this would have been better in a cream color, with or without the color on just the last round. Disappointing that I won't ever use it, but a good lesson. Sometimes it doesn't work to think outside the box! Live and learn. I'll save the beautiful HDTs for bookmarks and motifs!
Thread color choice is so important, just like it is with fabrics for quilting. It is definitely personal preference, but it is amazing how patterns can look so different with various color choices.
I am already choosing another doily pattern to work on. It will probably be in boring old cream this time :)
