Stardew Valley

There are a total of 94 items you will need to craft to obtain this achievement. They are all listed here: http://stardewvalleywiki.com/Crafting

While most of the crafting ingredients are fairly simple to come across and won't give you much trouble there are a few that you should watch out for and stock up on while you're playing that way you don't prematurely throw out items you'll later need or have to wait around for the correct season.

Ingredients to look out for

Now to actually obtain every recipe you need to meet a few other requirements.

Also, I suggest you create 3 empty treasure chests and then craft each item again that way you are sure you've crafted the item and not simply relying on memory. There are many crafting items you get gifted throughout the game and there's no in game tracker for what you have and have not crafted.

Under the settings tab, there is now an option to "Show Advanced Crafting Information". Enabling it will show how many times you have crafted an item when hovering over it in the crafting menu. Very useful if you are late game and have not been keeping up with what you have and have not crafted yet.

There have been new crafting recipes since the last solutions were written, plus some other changes to the game, so I feel like a new solution overhauling everything is needed. This solution is based on the 1.5.4.1 version released on February 15, 2021. In the event that there is a newer version at the time you read this, you can compare your list of items against the one here:

to see if anything is missing.

I have tried to keep spoilers to a minimum, but unfortunately, it is impossible to explain all of this without giving some spoilers.

PREREQUISITES
Before you can craft every item, you must have acquired every crafting recipe and have unlocked access to every required material. This is the real challenge in unlocking the achievement; collecting materials and using the crafting menu is just busy work. Below are the tasks or milestones you must complete before you can obtain all of the crafting recipes and materials. Some recipes are learned instantly, others arrive in the mail, and others must be purchased in a shop that unlocks when you complete the milestone. If you complete a milestone below and don't automatically get a crafting recipe from doing it, then keep exploring and look for a new shop that just opened up.

If you're unable to complete some of these prerequisites because you don't even know what they refer to, keep working on the prerequisites you are able to. Everything will come together in due time.

*NOT required in single player, but obtainable anyway. You can solo it, but you need two controllers. You DON'T need two XBox Live accounts. Build a cabin on your farm. This building has instant construction, so if it's Friday or Sunday, you can proceed immediately to the next step, which is to switch on local co-op in the Settings menu. Use your second controller to create a new playable character. As soon as that character joins the map, the crafting recipe you need will appear in the traveling cart. Buy it and then return to single player.

Some shops must be visited several times. Notoriously, you must go back to Robin again and again and again, buying 1 crafting recipe at a time, until until she runs out. Also pay special attention to visiting the festival shops, both for crafting recipes and rarecrows.

INGREDIENTS
The crafting menu shows you the ingredients you need. I don't think it's necessary to list every ingredient in the solution. Instead, here's what you're most likely to be short of, and where to get it:
Hardwood - Replenished daily in the Secret Forest
Iridium ore - Raise your evaluation from Grandpa to "4 candles" and pick up the Statue of Perfection from his shrine the following day. Before long, you'll have more iridium ore than you can use. See more here: http://stardewvalleywiki.com/Grandpa
Solar essence - buy from Krobus
Void essence - buy from Krobus

CRAFTING
You don't need to keep track of which items you've crafted or keep them in chests; the game does that for you. Simply pick "Show Advanced Crafting Options" in the Settings menu, and voila. Putting your resource chests next to a workbench and crafting at the workbench saves you from having to put everything in your backpack.

If you don't want all this junk you'll be making, buy a Deconstructor from Mr. Qi first and toss things into it after you've made them. This could also help your resources stretch further.

Since update 1.4 there are now 105 items to craft in the game. The additional 11 items from the solutions for 94 above are:

Wood sign
Stone sign
Garden pot
Warp totem: desert
Tea sapling
Tree fertiliser
Mini jukebox
Deluxe scarecrow
Brick floor
Grass starter

The wedding band is the 105th item, and is only available in multiplayer. I did make one in my multiplayer game but cannot say for certain if it is needed for the achievement!
