1) Adopt a charity and have a sewing meeting to make quilts or finish the ones people make at home.
2)Have folks bring their "unwanteds" (can be scraps, fabric they hate, UFO's, batting) for other members to take and use.
3) Have a "challenge" quilt (our guild has used a "crayon" challenge that was very well received. Guild bought a box of 64 crayons and dumped them into a brown sack. Each guild member had to reach in and choose one crayon. Whatever color they chose, they had to use it in a quilt. We set guidelines - no larger than 36" x 36", any technique, but color chosen had to be used on the front of the quilt. Amazing results!).
4) If guild can afford it - hire a "professional quilter" to do a trunk show and a class on their specialty. If guild can't afford it, maybe there is a member who is willing to "teach" her specialty. Charge guild members for the class - some goes to teacher, rest into guild treasury.
5) Have an "open sew" meeting where members can bring anything they are working on. Members are available to each other to help with questions/problems (a brick & mortar QB!).
6) Have a row round-robin. You begin a quilt with one row of your choice of fabric/pattern. You pass it onto to another member who adds a row and so on. Eventually you get back a completed quilt top. You can add fabric to your row to be used by the others in your robin, but cannot give pattern directions or likes/dislikes. (My guild has done this a few times. We kept the rows and fabric in clean, new pizza boxes. We had one person coordinate the robins. We were a large guild of over 100 members and each robin had 10 members in it. The coordinator kept track of the robins and who was in them and when to pass the boxes - usually at the monthly meeting. Worked very well with delightful results).
7) Quilting "Secret Santa" - at your holiday meeting do a secret gift swap of quilt related items. Set a price $15-$20. Make this a fun meeting. Lots of refreshments, sing carols, etc. At the end of year meeting (June?) have an ice cream social and a show & tell of all the projects you worked on during the guild year.
8) Do you have a program committee? If not, get a group together and discuss different ideas.
9) Technique meeting - set up different "stations" around the room and have someone teach different quilting techniques. Some ideas: different types of applique, paper piecing, hand quilting, FMQ using a DSM, crazy quilting...the list goes on and on. Do this as a round robin. Start groups at all stations, learn for a set amount of time, then switch. By the end of the meeting, everyone should have visited each station.
I'm sure if I really put my mind to it, I could come up with more ideas. Hope these few help. Feel free to PM me if you want more info or ideas.
Take care!
