Can I Have Your Advice?

Hello all.
I am getting married in September, and my colors are lilac and pastel yellow.
I have done pretty much everything but the decorations for the church, and the bouquets. I also have a strange church. There are two isles in this thing! So I figured I would walk down one with my dad, and walk up the other with my new husband.
Let me know what you all think about this, and if you have any ideas for how I can decorate let me know.
I am on a seriously limited budget now.
Thanks yall`
Heather
