Do not carry thread more than the space of 1-2 stitches under an area that is not or will not be covered with stitches. Otherwise your traveling threads may show through on the front as a "shadow".
For neater stitching on the front, work in rows, stitching each color as you come to it, thus eliminating isolated stitches* that can be easily detected by judges.
The magnets used in this product are VERY Strong rare earth magnets, so use caution.
* isolated stitch - a stitch by itself without neighboring stitches or a stitch of one color within a larger group of other colors.
Needle Park Avenue attaches to your fabric, near your working area, with rare earth magnets.
