You should now have 2 ‘stacks’ of strips with folds. Work on one ‘stack’ at a time.
Place a *folded towel on a firm surface and find your pin.
Make sure that the side with the drawn circles is uppermost.
Using the pin make a series of holes following the drawn lines. The spacing of the holes will depend on how large you have drawn your circles – make them roughly the same distance apart.
Make sure that that the holes go right through both layers. Hold up towards a light or a window to check.
*If you have another surface that is suitable for pricking use that.
Next stage following in the next scheduled prompt.
