Place the right sides of your outer fabric facing the side of the inner fabric that will be against the blade of the skate.
Sew a straight seam up each of the long sides of the rectangles.
On the terrycloth side of the rectangles, apply a length of elastic to one of the straight seams, stretching the elastic as far as it will. This is best done using a zig zag stitch.
Start sewing elastic at one end of the long seam. Make a few stitches, reverse, and stop. Pull the elastic to it’s full degree of stretch, and zigzag over the stretched elastic and soaker edge, as shown.
Repeat this to the other 3 seams.
Flip both of the soakers right side out.
Fold one soaker in half so that the long sides match up.
Fuss with the seam a bit, so the seams are on top of the fold that was created by flipping it inside out.
Line up the seams of the long edges on the sides, and sew the side seams with a straight stitch. Make sure you’re getting through all 4 layers of fabric.
Repeat with the other soaker.
Finish off side seams with a zig zag or Serger finish.
Turn soakers right side out, you’re done!
