Ferns and palms ...
Ferns and palms are made by gluing a wire (get a spool of 22 or 23 gauge wire from a hardware store) between two lengths of gummed paper tape. Let wire extend beyond paper tape for length of stem or trunk plus the usual ½″ for pushing into the base.
Bend paper over, trim, then slash. Make several, then twist wire “stems” together.
Paint fronds with poster color, water color, or latex white with casein colors.
If “fiddlenecks” are required, they can be made from pipe cleaners and twisted in with the wire stems of the fronds.
