Easy! Drop off come back in a few weeks and be amazed at there incredible craftsmanship. They will meet or beat the other shops in the area and if that is still not good enough they will work with you on the price. Very fair, very friendly and they have chocolate and dog biscuits.
They are the best. They have the knowledge and the "eye" to pick the best elements to use for framing artworks. In some cases they have restored and reused the original frames we had because they were chosen by the artist and decorated by him. They did a wonderful job each time. We have never used the DIY option (because we are lazy) but I'll keep it in mind for straightforward things.
