You have just started down a slippery slope.  Nice pens by the way, better than most for first pens in my opinion.  Most people, including myself made ones that looked like wasp bodies.  I did the pen thing several years ago, got so everything I looked at I thought I could use that in a pen... pinecones, feathers, bugs leaves... It was really a fun hobby... I did a lot with wine bottle corks.  but, yep it can take over.  Fun hobby and something that makes great gifts and conversation pieces.  Have a great time.. form there I want to cigar box guitars... still have a collection of cigar boxes.. another fun one.
