Chronic myeloid leukemia (CML) is a rare type of blood cancer and occurs when the bone marrow makes too many of one type of white blood cell, called myeloid cells. Almost all CML cases are caused by an abnormal chromosome called the Philadelphia chromosome.
These are new 18X24 Quality Picture Mats. The Openings are Bevel cut 12.5 x 18.5 to fit a 13X19 photo or print. These mats are cut from Quality white core mat board and are excellent for framing photos or prints.
The size of the mat and ultimately the frame, glass and backboard build off of that measurement. If you're framing an 8 x 10 picture and make an 8 x 10 frame, you will have no room for mat board. You have to make a larger frame, for example, an 11 x 14 frame so you can put a mat around your 8 x 10 picture. Use these charts as handy guides to help you plan your project.
