The Caroline brush is one of my favorites !! I love this brush because it resembles a watercolor consistency and is perfect for calligraphy and lettering. The second and third pictures show you the size and pressure/ opacity range of the brush. You will need to use procreate to download this brush and I recommend an Apple Pencil to create the same effect. * Nothing will be mailed to you, because this is a digital product. * This brush can be used for commercial and personal use, credit is appreciated but not needed. Please do not claim this brush as your own, resell it, alter, etc. Thank you so much ! If you have any questions or need help downloading please let me know! -LetteringwithLexiCo.
