You can always use any fabric that you want on any project. However, since this is an Imaginating pattern you might want to try 28 count over two stitches. The reason is that this company tends to use a lot of fractional stitches. NEVER feel that you have to use the "suggested" supplies. Substitute fabrics and flosses into whatever suits your fancy. Think outside the box. Make your finished piece different than someone else's that is using the same pattern.
