Thread Replacer 117.
This will give you the nearest five colours to any other colour in the DMC Article 117 colour range. Perfect for when a chart calls for a colour you don’t have, see if you have one that is close enough to go unnoticed? Not happy with a colour want it to be slightly lighter or darker?
If it saves you buying 2 skeins its paid for it self!
