I know the tags in Designs stop at K, that's a pity. Only thing you can do is search the different pages - I just happened to find one by clicking on a couple of pages - see link below.
Under Alphabets you find all alphabets in the left hand column. You won't find the St Patrick font as that is to be found on CuteAlphabets.com
Happy hunting!
Instead of using the alphabetical listing which is incomplete I went to the bottom of the page where all pages are listed. I started with the oldest one and downloaded what I wanted (most of it) and worked my way to the most current. Hope this helps.
