Review on 5-In-1 Sliding Gauge Sewing Tool Measurement Ruler By YEQIN by Marcos Woody

The "0” is when you push it all the way forward gently one notch before the 1/2 mark. The black line by 1/4 is "0”. At the other end is a 5/8, 1/4, 1/8 marked in black lines. The clear circle below the marking might need to be on your fabric a little ways. The 8 clear notches pressed in the yellow plastic before "1” inch and starting at the 1/2 marker help you count back to 2/3, 5/8 gently pulling the green slider toward you. Be gentle with plastic and don’t let your people rough house with it.
