For each part of the garland you will need everything doubled.
For the snowman motif part you need two circle snowman motifs and two scallops, larger than the circles. Glue each circle on one side of each scallop. Take a long nylon thread line and sandwich it in between two scallop motifs. Next you will sandwich the nylon thread between two stars. The distance between the scallops and the stars are up to you. Continue alternating between scallops and stars until the length you need has been achieved. Hang on the tree when finished.
