If you ever buy online, consider signing up for Easyfunding.org. Each time you go to a site through Easyfunding and buy something the company will give a small percentage of the sale to the meeting house fund. Downloading their 'Find and Remind' widget makes it even easier to do.
And at a bit more expense, there's an Etsy shop which is selling some items for the appeal - not all the items, so read the listings.
