Enchant an Item and Permanency are literally 1e PHB spells explicitly for the creation of magic items. The 1e DMG doesn't say it requires the breath of a falling star and the like to make magic items. This is what it says.3E was the first edition to have detailed magic item crafting rules in the core book. "Crafting" in TSR editions was essentially all GM fiat, what with having the capture the breath of a falling star or the sound of a distant moon or whatever.
"With respect to the former, you must determine which spells and ingredients are necessary to the manufacture of each specific magic item. For example, a player character wizard of 15th level desires to make a ring of spell storing. He or she commissions a platinumsmith to fashion a ring of the finest quality, and pays 5,000 g.p. for materials and labor. He or she then casts the enchant an item spell according to the PLAYERS HANDBOOK instructions. As DM, you now inform him or her that in order to contain and accept the spells he or she desires to store in the device, a scroll bearing the desired spells must be scribed, then a permanency spell cast upon the scroll, then the scroll must be merged with the ring by some means (typically a wish spell). As all of that could not be done in time, the ring would have to be prepared with the enchant an item spell again. Of course, you could tell the player before, if you are soft-hearted or he or she is intelligent enough to ask before starting the ball rolling."
So, you need to know the spells, just like with 3e. Then you need to have the finest materials to use, just like 3e. And then you need to spend the money and time, just like 3e.
