Newbies are not returning my thoughts...
Why? not feeling welcome?, feeling intimidated/too hard?  Coming late to lesson and being lost/confused during dance?  Lack of feeling of mastery/learning?  Need follow up lesson since we only dance 1x/month?  One month is a long time to wait for another lesson.  Not enough younger dancers like themselves?
Ideas:
1. Use beginner friendly buttons
2. Ask experienced dancers to dance with beginners for first 2 dances at least.  Board members lead by example.
3. Encourage experienced dancers to come for the beginner lesson to welcome/socialize with new dancers.
4. Have caller or one of us give out free passes (pass for next dance) at the lesson so we don't have to remember to do it at the table.  We gave out 15 free passes to new dancers in Feb and did not get any to return in March. (March dance was on 2nd sat instead of our normal 3rd sat and it's spring break.  Feb attendance 61, March 38 (paid dancers, not including 3 listeners).  Also there was a local magazine article about LBDA in February and we had our most experienced and popular contra dance band (Kaw Creek) playing.
5. Our Lesson is at 7:00, Dance 7:30.  Should we use start time 7:00 in advertising bc experienced dancers will figure it out and adjust to coming at 7:30 more easily than new people knowing they need to come at 7:00 for the lesson.  New people attending and being on time for 7:00 lesson is important for a smooth dance so do we need to advertise that way?  Want experienced dancers to be there to meet and socialize with them so they can be better integrated into the community and not feel so awkward.  I have suggested this to our board before, but was told that would be manipulative toward experienced dancers who would be upset that they came too early and wasted their time.  That feels like a very unwelcoming attitude, and I would like to encourage all our dancers to consider that 7:00 is our start time because beginners are important and we need to be there to greet them and socialize.
6. Schedule a 1 hour lesson or series of lessons led by experienced callers Lisa and or Jill and a couple new callers... before the dance?  On a different day?  Through Parks and Rec this summer?
7. New dancers are far outnumbering experienced dancers.  Need to do advanced dance to pull back in some dancers who drifted away after the pandemic.  Contact individually by phone/email?

And then getting younger people to attend is a whole other but strongly related topic we need to address more effectively.  We are not getting enough young people at dances.  It appears to me that when a young person comes they often decide to not return because there aren't enough people in their age group. 
 
Please tell me if you like/encourage these ideas I have come up with so far and add others.
Especially I want to know how to get new people to come on time for the lesson. 
Is it ok to advertise dance for 7:00 even though first 30 minutes is lesson?  It's frustrating for our callers and then they don't get a full lesson which is not good for anyone.
