I bought the chalk for my Nähhobby. I am a beginner. Unfortunately was not in the description that this works very well for solid cottons. I sew a lot with Jersey and as you can see, unfortunately, nothing. For me it was unfortunately a bad buy. But when you work with solid cotton fabric it is really great. One sees the chalk very well and they blur not easily be washed and it is also. Therefore, 2 stars for the chalk.
