I think it would be pretty easy to blend into the future than the past. Though I don't think in either case you'd necessarily be outed as a time traveler. The past, you're a witch. The future, you're just a crazy person.
Nah the future, you're like your grandparents who don't know how to Google, but so much worse. Technology has progressed so far, we wouldn't recognize it, but it'll have been taught from. Society will be so fundamentally different that we don't even have the context to discuss it here. The past, we can make suppositions, and while some will be wrong, we have some idea of what it's like, but the future, we'd be like a Napoleonic war veteran running out of gas in his car because he can't read the dials, didn't know what gas is, and can't use a gas pump because he has no bank account and cannot open one without a social security card.
Technology still needs to be designed to be used. Think of all the technology that still retains its basic form and only the material it's made of significantly changing. The Boomers that call for annoying tech support questions are just refusing to learn a new skill.
Yeah, I don't think spoons, and sandwiches, and socks are going to change that much. Most 'tech' changes a couple of times in a single lifetime (this was true even several hundred years ago), but the basics stay largely the same. Language is how they'll catch you
