DIY Wedding decorations

So, my fiancé and I are having our wedding next year (December) and I wanted to make the centerpieces myself. It’s a small wedding, only 70 guests. So we have 7 tables, one for us, one for the cake and I wanted random decorations (welcome sign, etc.) I’ve already found a lot of stuff on Hobby Lobby that I could use. So, if anyone has done this, drop some websites where I could find rustic items for my decorations ^_^

Just in case, we want to do something like these

Thank you!
