Item details

I originally made this simple little tool for myself, to help me spin the yarn weight or thickness of singles I want, and to be able to spin that weight consistently.

The PDF lets you print your own cards:
The first card shows the width and WPI of singles that fall around the middle of each of the yarn weights. I also use this card to identify mystery yarn from my stash.
The second card shows the width and WPI of the single I need to spin to make a 2-ply yarn of the desired yarn weight.
The third card likewise shows the width of the singles needed for a 3-ply yarn of the desired weight.

I keep one for each spinning project, often with annotations about the yarn I'm doing scribbled on it. On the reverse of each of the cards is a quick wraps-per-inch (WPI) gauge and WPI ranges for the common knitterly yarn ranges.

About Printing:

It is important to not let the PDF reader or viewer program resize the cards when printing, because unfortunately different PDF viewers and printer drivers resize documents differently. This is why I included the scale in the PDF. :)

There is usually a "auto fit", "zoom", "page handling" or "page scaling" option in theorinting options, and it's importand to set it to "none".
In the two different pdf readers I have, I set the print option "page scaling" to "None".

If it is set to "shrink to printable area", everything will print smaller than intended. How much smaller things are printed depends on the program, the printer used, and the print settings.

In my Yarn Theory Card ( listing you can see more information about the yarn weight ranges I used when setting up the cards.

I had to print a few time to get the sizing right. Other than that it’s great!

This is really helpful to me. I love that I don't have to remember the different WPI number for 2 ply or 3 ply it is right there on the chart

Great tool! Especially the 2- and 3-ply single widths are very useful.
