The instructions for the scrubbies are at Make and Do Crew I ended up using the bags noted as NOPE in the tutorial. Cut them wide enough to include at least 2 full diamonds so they didn't fall apart. Then a tug to make them behave. This also means that I needed twice as many produce bags as recommended. I also ended up just tying bits together with square knots, not the fancy fisherman's not suggested. It also turns out to take 4-6 bags to make 1 scrubbie with this style.
So excited to use up all my saved bits. But a little discouraged that it takes so many to make a functional piece. (Since what I thought might be 10 Christmas gifts is actually 2).
