Can you remove pencil lines of your cross stitch fabric?

That depends on the pencil you used when marking your fabric ;-). We sell washable chalk pencils in our shop. You can simply remove lines made with those pencils when using water. Alternatively you can use calcium tablets that seamstresses use.

Using a pencil is handy to grid your cross stitch fabric when working on larger counted cross stitch fabrics. With a grid on your fabric it is easier to count where you are on your pattern.
