I just finished a bright multicolored star with some black solid blocks and borders. I couldn't find anything that went with all the colors so used invisible thread on them. Then couldn't find a solid color I liked to use on the black so I wound up using King Tut #933 which is multicolored. It was a heavier thread than I have ever used before so my imperfect stitches are much more visible! (Everything I do seems to be a learning experience.) LOL
