As I am still hooked on dishcloths, I have been promising to write about a couple of things concerning their care and end results.
First off, lets talk about weaving in the loose ends after you have finished binding off the edge. The best method I've seen (no, I've not tried it yet), is the Russian Join. If you will go to this link, it has very good pictures along with the explanation.
Second, is the subject of setting the color - especially, since there are some bright color combinations out there, along with the fact that laundering will zap that color quickly. From what I have read and also discussed with Heleen, the following seems to be the best suggestion:
Pour vinegar into a container with warm water and soak the dishcloth for an hour or so. Remove from water and roll up in a towel to remove excess water - DO NOT RING. Let dishcloth air dry. After this procedure is complete, you can launder as normal. To add on to this info - you could play it safe and use the detergents that are for dark laundry only - another suggestion from Heleen.
If you are giving the dishcloth as a gift, you may want to include a note explaining how to keep the color bright.
Hope this helps. In fact, I hope this works - LOL. I guess, one way or another, we'll all find out sooner or later. If any of you have a better suggestion, by all means, PLEASE let me know.
