Cheers,
I have been part of a guild forever....try an auction, members buying tickets with donated can goods for charity, or fat quarters to raffle off for another project. Memeber get to bring in there jnque.
Use your memebers talents also. Maybe there is a fabric store that would come vist giving members discount tickets, they could show what's new for fabric lines.
Also make up a brag book with member talents, sew new ones can see who does what technique or style they may want to learm
hope this helps.
:)
