Every wizard knows the importance of keeping their spellbook and their spell components close at hand. This handy belt bag will allow you to do both in style. The scalloped fold provides an extra layer of padding for delicate items like rose petals or vials of pixie dust. The secure button and double hooks will encourage pickpockets to look for an easier target, and the decorative edging will keep your tome securely in place.
This pattern is sized for a standard traveling spellbook. Wizards who use a tome of exceptionally ornate size or decoration may need to make some modifications. I don't recommend using this bag to carry either the fulminating treatise or the tome of the stilled tongue: The former is likely to set the wool on fire and the latter is too large (and, honestly, too gross) to fit neatly inside.
