I’ve made this booklet “Warmups & Such” that you can print out. I think it will be really handy for warming up your fingers before a play. It includes:

Simple scales (pentatonic / major / minor)

Strumming patterns

Chords (Power chords / major & minor barre chords)

Changing keys

Fingerpicking patterns

I made a Youtube video (above) of how to print and make the book, then how to practice with it. Click here to download the .pdf.
