Would love to join as this sounds like it will be really fun! The only mystery I've done is one my MIL started and got mixed up assembling it and I tried to figure out how it was supposed to be. Finished up really pretty, even though I would have picked different fabrics as my taste differs from hers.
Will be a little late getting started as I will be out of town the next two weekends and very busy in between. But I'm sure I can eventually catch up.
