There are times when you really have to frog a project even if it looks counter productive. I made a mistake on my recent project. The triangles are much too big compared to what I imagined them to be, so even if I spent a lot of time completing them.. I frogged 5 rows off each triangle! And there are 20 triangles in there..
I feel much happier with the smaller garlands..
So, when do you have to frog the work?
1. When there is really no way that you can be happy with the output unless you frog it :)
2. When you really can't make any other work around that certain "mistake".
