If you are like me, you have a a tape maker in your sewing room that you used long ago and have long since misplaced the package with the instructions. I wanted to use mine yesterday so I did an internet search and found the information. I did not find it on the PR site so I thought I would post it for every one's reference.
The Clover set comes color coated and has the mm size engraved on them. The single fold width is Green =1/4", Yellow = 1/2", Red = 3/4" Blue=1" and Gray = 2". The double fold is 1/2 of those measurements.
The strip to cut is 2x the single fold width. For example the Blue 25 mm bias maker needs a strip 2" wide and will make single fold bias tape 1" wide and double fold bias tape 1/2" wide.
I have now taken a Sharpie and marked the strip width on the metal bias tube next to the mm marking. No more trying to remember or wasting sewing time on the internet!
My set does not have the slot to feed in fusible web but I understand they are now available with this feature.
I came across this on line tutotial that I think answers almost every question I had.
