I will definitely never do another Dimensions kit again. I am certain I will run out of the red floss used in the heel. What I am doing now is stitching a row, leaving a row blank, stitching a row, etc. I will then go back and fill in the gaps with whatever floss I have left. If I do run out, I will have to substitute DMC but at least the new floss won’t be in one big block area, which would stick out like a sore thumb. Hopefully if I do have to substitute, it will be subtle.
