Coverstitch Clear Presser Foot fits MCS-1500/MCS-1700QVP
Since this type of presser foot has a transparent foot, allowing the operator to see stitches and material while sewing is helpful.
In the case of the looped part, such as the t-shirt hem, this foot will assist you in seeing the needlepoint so clearly to overlap the stitches at the end of sewing with the beginning one.
