Thank you to your suggestions for keeping the chains uniform. I was stubborn and refused to measure the chains. This is the result. After tatting, I need to push the stitches back. This is when the chains get uneven. It will have to do.
So far I have used Lizbeth Size 20 in Col. 620 Azalea Medium, 702 Coral Orange Medium and 184 Rainbow Splash. It sure is very colourful.
