One thing my guild did last year I enjoyed - one month was "Quilt Bingo". They told you a couple of months in advance to make quilt squares for bingo cards. 2 1/2" squares; row 1 red/pink, row 2 yellow/orange, row 3 green (with a black square in the middle for "free"), row 4 blues, row 5 purples. Within your colors you had catagories like solid, floral, stripe/plaid, novelty, metallic, ect. So you could make and bring up to four (4) 10 1/2" blocks to play bingo. Some volunteers made extras and you could pay $1 to use those if you didn't make your own. They would call "blue, novelty", ect. They had donated prized for winners. The blocks (cards) were collected to sash with black and make charity quilts. It was a very enjoyable event.
My guild does an annual challenge quilt with a common fabric or theme - you have to buy the FQ at the meeting ($3) and have 3 months to turn in your entry. They have to be small (max 30" sides). They are displayed at LQS afterwards.
We put on a show in odd-numbered years at the county fairgrounds. To hold the building, we use it every year the same weekend. In even-numbered years we have quilt college. For quilt college, guild members teach 1/2 day classes to other guild members for free and the registration fee for 2 days is minimal to pay the building rental fee (like $15 for up to 4 classes). Takes a lot of organizing but they have been doing it a long time and have it down.
