We have done fundraising each year. The letter writing campaign is the most effective and time efficient way to raise funds for us. We put a picture of our daughter and son on the letter and make it personal. We get donations from people we don't even know. It kind of ends up taking a life of it's own, year after year. For example a woman my dad works with saw the letter I sent to my dad and decided she wanted to fundraise, she raised $500 on her own and brought her whole family to the walk(7 year old twins & a 5 year old) walked with us and again I met her at the walk. I send the letter to everyone I can think of. E-mail is also good. We set up a webpage last year and people can even use their credit card to make a donation. It was super easy.
I also like people to "get" something back for donating, one year i bought like 50 of those blue Cf bracelets and everyone sho made a donation got one. My sisiter's friend made up "Maggie's Marcher's" t-shirts and for a donation you can get a t-shirt(people love those)
Just a couple weeks ago, i had a Tupperware party(my friend is a consultant). 40% of sales went to CFF. we made $400 for CFF in one night. It was very easy too. I just made sure I had plenty of wine and snacks for the ladies and we had a great time.
Also, other family and friends can walk in their part of the country if they don't live near you. I just got an e-mail from an old friend of mine who is a soccer coach in NY and she is setting up a Maggie's marcher's team for her soccer team and they are going to fundraise as well with a goal of $5,000.
Another friend of my SIL is planning on running the Boston Marathon in April for CF. You have to raise $2,500 to do this in Boston, Cool huh?
Year after year people come up with these ideas and it never ceases to amaze me.
My daughet's ballet teacher even said this year she want to sell flowers at her recital for CF(roses and carnations). parents buy them anyway for thier little dancers but this year it will benefit CFF.
Good luck
