If your congregation is looking for high-quality, low-cost (most are free!) liturgical art, you’ll want to check out suntreeriver design at http://suntreeriverdesign.blogspot.com/. The 2012 Lenten has just been posted. Every piece that you see online is available for your congregation to use free of charge so long as you credit ©suntreeriver design.
Images are searchable by season from the hyperlinked tags on the site.
If you’d like high resolution, printable pdfs (though the jpgs on the site will print fine at smaller sizes) for bulletins, posters and so forth, you will need to contact suntree river design via email (suntreeriverdesign@gmail.com). Suntreeriver can also provide, for a nominal charge, updated or not specifically dated versions of designs that carry a specific day and year.
