The quality of this is incredible. The slider stays where it is placed, excellent value for money.
Wasn’t sure if I would need it but it looked useful so popped it in the basket and have found it invaluable for measuring seam allowances and patchwork pieces - speedy delivery too
Great item a must have for sewers. Great for hemming small things like armholes or adding on a seam allowance.
I find these a very useful gauge, several are in my stash.
