Take a panmagic 5x5 square and add 12 to all numbers, so in the 5x5 inlay are the 25 middle numbers from 13 up to 37.
In the border are the 12 lowest (1 up to 12) and the 12 highest (38 up to 49) numbers. Read the explanation on webpage 3x3 in 5x5 & concentric, how to construct the border.
See in the download below how the 7x7 border has been constructed or use the download to puzzle your own border.
The result is:
