This is something my husband and I have been working on. It is not quite finished yet: need to put the photos up (after the baby is born we will take a few) and also we have a little alphabet to put up.
Reuse/Reduce/Recycle :) We reused quite a bit, as well as I have made a lot of things myself: Crib sheets, blankets, covers for the change table, curtains. We reused furniture from long time ago and made it "fit".
IKEA mostly for the furniture, Local Winners store for the little items, table, lamp, change table top. Fabric Land - look for the sales, as the fabric you can get there is amazing for baby stuff. UBBI for the diaper pail
