There are many items to craft in Stardew Valley and many are fairly straight forward early game items. The full list can be found here - http://stardewvalleywiki.com/Crafting
I personally would recommend keeping a small note of which you have crafted, in order to make things simpler, and would definitely recommend trying to get the craft all items achievement while you are at it.
30 shouldn't cause you too much trouble!
Good luck and happy hunting.
