One of my most favorite resources for free downloads is Wedding Style Guide. On their site they offer tags, labels, party decor, packaging accents, and more...all beautifully crafted around a specific theme (many of their designs can be customized with your own text too). These Book Club downloads (for example) are some of my favorites — and just in time for New Years, they have this charming New Years Party Download Set (yes, free...can you believe it). 
You can see heaps more right here. xo Ez
