Materia Crafting allows you to make your own Materia from your items. Acquiring this skill is actually a part of your Main quest, no matter which class you are. It's a Level 19 quest that sends you into Central Thanalan to talk to a Goblin named Mutamix Bubblupots. After completing this quest, you'll have to ability to craft your own Materia.
It might be smart to hold onto older equipment instead of selling it right away. You'll know that an item is ready to be crafted into Materia if its Spiritbond is a 100% and the description states that item is Convertible. To get a 100% Spiritbond, you just have to have that particular equipment on, and use it in the field enough until it reaches 100%.
Materia melding requires any of the Disciple of Hand classes to be level 19 or higher. This quest, Forging the Spirit, is found in the same area as the previous Materia quest, in Central Thanalan at the Bonfire.
Aside from needing equipment with empty slots, the appropriate Crafting class level and the Materia you want to slot, you also need Carbonized Matter, which is used to affix the Materia into the item. Carbonized Matter comes in five levels based on the Materia you're slotting.
