Try making your own nail polish with old eye shadow you don't use anymore or perhaps they are old and you don't want to throw them away.You will need a clear coat nail polish, pigments such as eye shadow or NYX pigments. Put a little pigment on a plastic lid and pour clear coat onto eye shadow. Use more clear coat than pigment. Mix thoroughly and brush on nails. If you like the color and want to keep it, take an index card and fold into a cone like shape. Put bottom of cone into the nail polish bottle and put eye shadow or pigment into clear coat. Put the lid on bottle and shake to mix pigment with clear coat. You have made your own nail polish!
