It's that simple:
Cut a strip from Felt sheet in the size 17 x 45 cm
Next, draw ten 3 cm wide strips on the Felt , with 1 cm distance to the edge. Mark 1 cm between each strip. When this is done, the felt strip is cut off 1.5 cm after the last strip
Now mark the cuts for the test tubes within the strips. Alternate 2 and 3 cuts per strip.
Now cut open the markings with pointed handicraft scissors and put the test tubes through
Roll up the felt strip evenly and secure the bundle with rubber bands.
You can wrap paper wire, decorative aluminium wire or natural bast around the bundle as you wish and twist or knot the ends well. You should hide the wire ends behind a Test tube
At the end you can glue small quilling flowers with hot glue, put big quilling flowers or real flowers into the test tubes and fill them up with decorative gravel.
