I knew I couldn't change thread colors along the border, so decided to blend in the color change around the corner.
Sorry for the bad lighting here, but what I want to show you is how I left gaps between the stitching around the corner, and then I filled in those gaps with the new thread color, and I think it worked.
Ignore the chalk lines, and I don't think you can really tell the new color from the original color.
Thank you all for the positive comments on my progress report. I really appreciate them. Here is a funny story about that post. I wrote it up on Saturday afternoon, and thought I posted it then. When I came back later that weekend, I checked, because really, don't we all like to see if there are any comments? There were none. Well, okay, so no one left a comment, or read my post, maybe no one reads on the weekends. Well Monday came, and still no comments, not even from my "regulars" I know I had been very lax in my blogging, and was starting to think maybe you all got tired of waiting for me. I did some more checking, and it turns out I didn't publish the post, I just saved it. When I actually did post it, you were all so generous with your comments and compliments, it made my day. Thank you.
