The green painter's tape comes in 1/4" width and I have used it to make sure I am getting an exact quarter inch seam and it comes off the fabric very easily and then started using it for marking in several different ways (rulers, patterns, etc) and since it is only 1/4", it comes off very easily and I use mostly vintage machines and can put it on the bed out from where my quilting foot begins and it has been extremely helpful teaching my 9 year old granddaughter to make nicely done seam allowances. Then I can just take it off the bed with no damage at all to the surface of these older machines. My Featherweight was extremely please with it ;-).
