This is the one where scrapbooking meets knitting!
I have been wanting a WPI (Wraps Per Inch) tool to check the thickness of my wool for some time and I didn't get around to buying one so I made one from chipboard and patterned paper.
For those of you who don't know, although I think you all probably do know, a WPI tool is used the determine the thickness of the wool you are using and it is particularly useful when you have some wool that seems to be a different thickness to that which you were expecting or when you have lost the ball band and don't know what the yarn is. By wrapping your yarn around a WPI tool you can count how many times the yarn has been wrapped within the inch and this will help you to determine what weight the yarn is. Here is a little guide:
Here is how I made it (Click images to enlarge them).
Draw a 4" x 1" rectangle onto a piece of chipboard and mark a 1" notch on one side and a 1/2"notch on the other side.
Carefully cut out the chipboard piece using a craft knife. Do not try to cut through the entire thickness in one swipe of the knife, instead press more lightly and make several passes along the line (against a ruler) until you have cut right through the piece, this makes a much neater edge.
Use the chipboard piece as a template to cut out two pieces of patterned paper. Remember to flip it over to cut the second piece so that the notches are in the correct place.
Paint the edges of the chipboard with some white acrylic paint. Allow to dry.
Cover the chipboard piece with Mod Podge.
Attach the paper to the Mod Podge and smooth it on using a brayer (or a rolling pin).
When you have attached the paper to both sides, cover the entire piece with Mod Podge and allow to dry.
Round the corners with a heavy duty corner rounder such as a We Are Memory Keepers Corner Chomper or a Bind It All corner rounder.
Punch a hole in the top of the tool and thread with a ball chain so that you can attach it to your knitting bag.
If you want to further protect your WPI tool make a little cover for it using a CD wallet and some pretty washi tape :)
