Holiday cash: How to create & sell T-shirts without ever touching inventory

Let’s talk T-shirts. Not the boring kind. I’m talking about clever, seasonal, giftable shirts people actually want to buy.

Whether it’s a “Dear Santa, I Can Explain…,” “Sleigh My Name, Sleigh My Name” or “Resting Grinch Face” tee, custom tops make great holiday gifts. And thanks to AI and print-on-demand, you can start a T-shirt side hustle from your couch.

No design skills, inventory or shipping labels required. Yes, really. 

🧠 Step 1: Brainstorm ideas

Start with a tool like ChatGPT to generate concepts and slogans. Prompt it like “Give me 15 funny Christmas T-shirt ideas for dads.”

Want niche ideas? Ask for Christmas wear for gamers, teachers, dog moms or pickleball fans. AI is a gold mine of clever copy.

🎨 Step 2: Use AI art tools

Use Canva, Kittl or DALL·E to design a shirt graphic. You can even generate original art like “a cool cartoon Santa lifting weights” or “retro-style gingerbread cookies doing yoga.”

Keep your designs clean and high-contrast. Save as PNG files with a transparent background and 300 DPI resolution.

🛍️ Step 3: Make money

Upload your design to platforms. They list the items for sale, print the design on the item, ship it, collect the taxes, and the rest. You make the money.

  • Amazon Merch on Demand: You earn $2 to $8 per shirt, depending on the sale price and type (standard, premium, long sleeve, etc.). It’s on Amazon Prime, which boosts visibility during the holiday shopping season.
  • Redbubble and TeePublic: Set your own profit margin. Most creators make $3 to $10 per sale.
  • Etsy + Printful: Combine AI art with Etsy traffic. After production and fees, you’ll typically earn $5 to $15 per shirt, depending on your pricing and upgrades (like organic cotton). Btw, this is how I run my Etsy store that, wow, needs love. I promise to work on it!

🛒 ChatGPT goes checkout: If you’re in the U.S., you can buy Etsy stuff inside ChatGPT. Shopify’s next. It’s single-item for now, Stripe handles payment, and merchants pay the fee, not you. Amazon and Walmart aren’t playing (yet).

💻 Time to leave Windows 10: Support ends Oct. 14, and even with an extra year of security updates, it’s best to move on. To upgrade, go to Settings > Update & Security and click Download and install Windows 11 (at the top). Don’t see it? Get the Windows 11 Installation Assistant online and follow the steps. Need a new PC? Here are my picks.

⚡️ 3-second tech genius: If an app, service or your internet seems down, check Downdetector. Search the name to see current outages along with problems reported in the past few hours. And if there are none, reboot your device. 

Raycon’s anniversary means 20% off the Everyday Earbuds Classic! I love their comfy fit, Active Noise Cancellation, Awareness mode and up to 32 hours of battery life. Grab a pair with my link and see why fans love them: BuyRaycon.com/KIM.

🦆 Ducking autocorrect: Nothing’s worse than your phone “fixing” words you meant to type. On iOS, go to Settings > General > Keyboard > Text Replacement to add your own. On Android, go to Settings > System > Keyboard > Personal dictionary. Or just type the word, tap it in the suggestions bar, and teach your phone who’s boss.

Cable hoarding pays off: That tangle of old cords in your junk drawer? Some are weirdly valuable. GameCube cables can fetch $200, and even a dusty SCSI might score $50. Before you toss that HDMI doppelgänger, check eBay, nerds will pay. Turns out nostalgia is profitable, and so is not cleaning your garage for 15 years. Check here to see how much your old cables are worth.

📖 Make your Kindle feel like a real book: Love this little change. Go to Settings > Screen and brightness > Show covers on lock screen

Ears the catch: Apple’s new Live Translation feature is finally coming to older AirPods (yay!), but there’s a catch. It only works if you also have an iPhone 15 Pro or newer. So unless you’ve got a $1K+ phone and the right earbuds and iOS 26, it’s back to Google Translate and hand gestures. Or get the new AirPod 3s. The heart sensing and live translation is so good.

A cloud in space: At Tech Week, Jeff Bezos said the AI boom will push massive data centers into orbit within 20 years. Basically, solar-powered, gigawatt clusters will beam information back by laser. He swears they’ll beat Earth’s power costs. Oh, a wild footnote from that talk? He predicts millions of people living in space, too.

🤖 Extortion, but make it software: Just a reminder, Microsoft’s killing Windows 10, and support ends Oct. 14. I’m sure hackers have the date penciled in their calendar. That’s 400 million computers going vulnerable overnight. Want security? Pay up, or replace your whole machine. Low-income families, seniors, remote workers, kids with homework? Too bad, Microsoft doesn’t care. See my new PC recommendations here.

Paying too much for cloud services? Check this out. Oracle Cloud Infrastructure, or OCI, is built for speed, power and serious savings, without the usual cloud headaches. That’s why some of the biggest AI innovators trust it. Try it for free right now.

📱 Android app shortcuts: Long-press certain apps for quick access to core features. Chrome lets you open a new tab or jump into Incognito mode. Gmail gives you options like composing a message or switching accounts. Social media apps like Instagram let you post right away or check your activity feed.

🐾 Doggy surveillance default: Ring cameras are now default detectives, scanning outdoor feeds for missing dogs if a neighbor posts on the app. If your cam spots one, you’ll get a ping, but the opt-in switch flipped without asking. Amazon insists it’s only for pets, but facial recognition just launched, too. You can see where this is headed. Suddenly Fido’s not the only one being tracked. To turn it off: Open the Ring app > go to menu (☰) > Control Center > tap Search for Lost Pets > toggle off for every device. Good thing you have me on your side.

🕵🏻‍♂️ Keep your email private: Free email providers like Gmail and Yahoo track what you do. I use StartMail because it keeps my inbox secure, stops spam and keeps my personal info private. Try it free for 7 days, and when you sign up, you’ll get my 60% off deal for the first year!

⚡️ 3-second tech genius: Old Chrome extensions can slow things down. Click the three-dot icon (top right), go to Extensions > Manage Extensions, pick the ones you don’t need, and hit Remove.

🗑️ Don’t waste money on outdated tech: Before buying a cheap phone, tablet or e-reader, check if it’s still supported. Visit endoflife.date and search the model to see if updates have ended or it’s discontinued. If it’s past its prime, that usually means no more security updates, which is a big no-no.

Compare docs the easy way: Collabing in Google Docs can get messy fast. Skip the side-by-side chaos of spotting changes manually. Instead, go to Tools > Compare documents and select the other file. Google creates a new doc with deletions crossed out and additions highlighted. Lifesaver. 

💬 Reply from lock screen: iPhone makes it easy to fire off a text without fully unlocking. When a message pops up on your lock screen, just long-press the preview, punch in your passcode, and a mini Messages window with keyboard appears. Type, send, done. Fast replies, zero app hunting.
