It seems all water soluble marking pens on the market are NOT equal. I was devestated to find that the generic marking pen I had started using, faded in less than 4 hours to barely visible. The nib scratched across the fabric, which was uncomfortable to use as well as making it harder to mark the design. Then I changed to Clover, which marked really nicely, but the fine tip was also scratchy, it didn’t glide smoothly across the fabric. This was solved by putting the Clover “ink” cell into a no-name-felt-tip-like marking pen I really liked the feel of, however the original brand ink wasn’t that great to work with, pale and light coloured, so the combination of Clover and felt tip seemed to work very nicely. It is a case of buyer beware, water soluble pens are not all the same, as I found out after spending hours marking the DWR top with quilting designs. The weather has an impact on marking trapunto designs, as I found out 2 years ago, high humidity makes the ink disappear very quickly, so after waiting for a few dry days after/during times of flood, to have products fail me was pretty upsetting. Another lesson well learned. It hasn’t spoiled the excitement of stitching the design with water soluble thread tomorrow, so stay tuned…..
