Good job! Glass or no glass, that is the question. It has been discussed here many times. I use glass. If is a piece I am giving to someone special or keeping for my own use, I use an anti-reflective glass. It also helps block the UV rays. The primary reason to use glass is to keep out the dust. If you use a paper backer, it can fade in the sunlight. Your wood can also yellow in the sun. A lot of people use paper as a backer, I don't. It is a mater of personal preference.
