- Ivarstead - Fellstar Farm: (Spoon)
- Windhelm - The White Phial: (Soul Gem)
- Winterhold - The Frozen Hearth: (Orichalcum Ingot)
Talk with Wylandriah while in Riften. She will explain that she needs these items for an odd little experiment that she is working on. She claims to have misplaced them while traveling, so they are well scattered across Skyrim.
Getting this while in good standing can be tricky as you need to enter the house after everyone else has gone in. However, you can also just break in during the day at some point when everyone else is away and no guards are looking.
Go inside during business hours (or break in after them). Once inside, find the stair case. Look beneath it to spot a pair of barrels. On one of them is the satchel with Wylandriah's Soul Gem.
Once inside the inn, head for the shelving opposite the entrance. On one of them you will find the satchel with the Orichalcum Ingot inside it.
