Bridal Shower Question

[Lady Pi Phi]

I am the maid of honour for my best friend's wedding this September. There are 3 of in her bridal party, and the 2 other bridesmaids are helping me co-host her shower. All three of us are on a tight budget and the shower will take place at my house.

My question is, are favours for the guests necessary?? I have never been to a bridal shower where I was given a gift/favour for attending. I personally hate favours and I hate stupid little trinkets. I think they are a waste of money.

I don't want to waste money on favours, but I really don't want to pi$$ anyone off if I don't have them, but how can keep the cost down for favours?

I don't have a theme for the shower. Our plan was to keep it along the same lines as the wedding. Her colours are black, white and silver and a classic car theme (both bride and groom are classic car nuts and the groom is a mechanic).

Any ideas??? Do I really need to get favours??
