I wanted to make a small guide to people like collectors or just general toy buyers for children, who might want to know where to find various toys and such things when visiting Finland. First part will be about Helsinki and some general info on other places also.
So~ There's a high change if you are traveling to Finland, you end up at capital city Helsinki.
I'm a tourist myself since I have not lived there, but I certainly have been there for numerous times and gathered knowledge of various places where I like to visit.
Random basics for foreign travellers:
If you know or speak English you should survive just fine, most of the people in Finland know English. People can turn a bit shy or awkward when they try to speak other languages.
Don't ever start small talk or touch Finnish people, unless you are familiar with them.
If you want to travel when it's warmer, altought summers are still very cool, sunny and there's plant life, I suggest between May and August. July is usually warmest of months, but tempeture still rarely exeeds 30 celsius, but in direct sunlight it can get a bit hot.
If you want snow I suggest January and February. Climate change has turned November and December into pretty much snowless months in southern Finland and other months are pretty gloomy and cool also.
Remember to buy and use a reflector (Heijastin) during dark winter times. They come in all kinds shapes and colours/patterns. Many stores carry them, you can just attach them to bags or jacket's hem or if it's a strap version, jacket's sleeves.

I also would like to recommend Stockmann Herkku-section. It's a very fancy food store, contains lot of interesting food products which aren't available anywhere else. Prices are a tad bit higher than normally.
Kaivopiha, 00100 Helsinki
Store is located in Kaivopiha area, it's a bit hidden due to not being straight up visible from the streets.
There are signs outside. Just walk hallway down past Subway to the end and you will find the store.

Other noteworthy shops

Japanese products, some food items and candy, pottery like cute rice bowls and tea cups, kitchen utensils and kimonos.
Simonkatu 10, 00100 Helsinki
For your crafting supply needs.
I unfortunately have very limited info on this part.
Central Helsinki does have some fleamarkets, but they are mostly for clothing and such.
I also have not visited them much, so central Helsinki is not very good for finding treasures.
(Or I don't just have enough knowledge of such places)
Fida recycling centres do have toys, so take a look if you come across one.
You can ask me if you have any further questions.
