I tried to make a beetle dishcloth but that didn’t turn out too well, the end result was this little bug. It looks kind of like a shield bug I suppose, but not quite.
This pattern is written and includes a chart. The chart is made in colors instead of symbols, I personally find it easier to read that way. There is a chart key to help guide you.
I would recommend using any brand of 100% cotton. I find it works better than the cotton blend yarns when it comes to dishcloths.

I know that some people have been modifying the pattern (which is totally okay) so I wanted to add a link to the chart for this pattern on Chart-minder in case you would like to go to the source and edit what you need.
