First cut the florist's crepe paper into 50cm long strips (approx. 1.5cm wide). Then gather the strips in the middle once so that you have 6 of these strips bundled together.
Next, you only need to tie each bundle together with a winding knot (VBS craft tip: macramé winding knot).
Finally, you only need to knot the finished bundles to a long ribbon and your garden party garland is ready.
