Why not create your own blank tab sheets using a word processing program...that's what I do. I've got one blank MD tab template set up for a vertical tab page format with another set up for horizontal (for songs with long verses).
At the top of your word processing document, leave enough space so you can fill in your song title, MD string tuning, time signature and playing speed. Then, double space down and use the underscore key on your computer keyboard to create the three lines of music notation for the song tab (bass string, middle melody and bottom melody string). Leave enough space underneath the bottom melody line so you can type in lyrics. When you have the blank song tab template finished, save it using the file name, "Blank MD Tab" or whatever.
When you want to write out a new tab, just print out a copy of your blank MD tab template. Then you can type/write in your title and song information, your lyrics, and the notes/chords/comments for the song. You can use the blank tab template for song drafts or to type up your final arrangements and compositions.
Designing your own blank song tab gives you the flexibility to print out several blank tab sheets at once or print them as needed. Best part, they're free and customized to fit your needs. And you can always redesign the tab template as your playing skills progress...or regress. Hope this helps.
