Welcome to the forums @alphabeat and also in extension to your wife. You have come to the right place since all the lovely people can give you a lot of wonderful tips when starting to collect. This place is also filled with a lot of information you can browse but if you have something specific to start you can just ask away.
On the topic of slows, we already have an awesome member @slowqueen with a collection that you and your wife might love to see and also take inspiration from.
Have fun on the forum and looking forward to hearing more about your collections and collecting stories.
Cheers!
