The low-effort version of a Hogwarts Halloween party, for families who'd rather stay in on the couch.

A Harry Potter Halloween movie night is my favorite way to do Halloween with kids who are too old for the toddler parade and too young to be let loose on the neighborhood alone. You get the costumes, the candy and the spooky mood. The whole thing happens on your own couch, and nobody has to find parking.

This is the first issue of the Attempting Aloha newsletter, so hello! I'm Charlee. I've been blogging about DIY crafts, themed parties and free printables since 2010, and I have four kids who treat every holiday as an excuse for a theme. Halloween at our house has gone Harry Potter more years than not, and over time I've cut the evening down to five parts that fit between dinner and bedtime and cost less than one boxed costume.

Here's the whole plan.

The schedule (about 3 hours)

I write this on an index card and tape it to the fridge, because kids handle a party much better when they can see what's coming next.

Three hours is the sweet spot. Go past that and somebody under ten will melt down, and I promise it won't be the one you expect.

1. Costumes: keep it to robes and wands

You don't need full costumes for a night in. A black robe (a graduation gown, a bathrobe or a black sheet with a head hole) and a chopstick wand are plenty. If your kids want to go further, I wrote up all of our Harry Potter Halloween ideas, including the closet-only costumes we use every year.

One tip that saves the evening: put the costumes on before dinner photos, not after. A kid in a robe with spaghetti sauce on it is still a wizard, but the porch photo is the one grandma wants.

2. The sorting ceremony

This is the part my kids talk about all year. It takes ten minutes, and it gives everyone a team for the rest of the night.

What you need:

• A hat. Any floppy brown or black felt hat. Ours is a thrift-store witch hat I squashed and rubbed with a bit of brown eyeshadow so it looks old.
• Four house cards. Fold an index card into a tent, write the house name, color it in. Maroon, green, blue, yellow.
• A quiz. Before the hat goes on, each kid answers a few questions. We use my sorting hat quiz printable, and I tally the answers while the hat "thinks."

If you only have one or two kids, sort the grown-ups too. The night only works with at least two houses competing, and parents losing at House Points is half the fun.

A small honesty note: I quietly make sure siblings who fight end up in different houses. The hat considers your preference, after all.

3. The snack tray

I don't cook a feast on movie night. I build one tray in the afternoon and give everything a wizard name. The name does about 90% of the work.

Our standard tray:

• Popcorn, a big bowl, half of it tossed in melted caramel.
• Pumpkin juice: apple cider plus a splash of mango or apricot nectar, a pinch of pumpkin pie spice, cinnamon sticks in the pitcher. Kids drink it cold, grown-ups warm it up.
• Chocolate frogs: a $6 silicone frog mold and a bag of chocolate chips, melted in the microwave in 30-second bursts. Make them the day before.
• Jelly beans in a jar, labeled "every flavour." My kids hunt for the black licorice ones to give away.

That's four items, about $15 total, and none of them needs an oven. If you want more, my Harry Potter party food ideas post has the bigger menu we use for birthday parties. For tags, the free Harry Potter food labels print on cardstock and fold into tents.

4. Which movie, and the bingo break

For a Halloween night, I pick one of these two:

• Sorcerer's Stone for younger kids. The troll in the dungeon is a Halloween scene, and the feast is the best food scene in the series.
• Prisoner of Azkaban for ages 9 and up. It's darker and more autumnal, and it has the most "October" feeling of all the films.

About 45 minutes in, someone always needs the bathroom anyway, so we pause and play bingo. I use my old Halloween bingo printable from 2011, and the markers are candy corn, so you eat your markers when you lose.

Bingo rounds go fast, so we play three, and each win earns 10 points for the winner's house. That is the bridge to the last part.

5. The House Cup

Four jars, four colors of candy. Every time someone earns points during the night (bingo win, best costume, helping clean up popcorn without being asked), a handful of their house color goes into that house's jar.

My scoring rules, which my kids now quote back at me:

At 8:15 I announce the House Cup, the winning house picks tomorrow's breakfast, and everyone splits the candy from all four jars anyway. Nobody truly loses, and nobody needs to know that in advance.

What it costs

I tracked it last year:

• Chocolate chips and frog mold: $9
• Popcorn, caramel and jelly beans: $7
• Apple cider and nectar: $5
• Candy for the house jars and bingo: $8
• Printables: free, ink aside

That's about $29 for the whole family. Our neighborhood Halloween carnival costs $10 a person before anyone buys a snack.

If you're short on time

If it's October 30 and you're reading this in a panic, here's the bare minimum, in order:

1. Print the sorting quiz and a bingo card.
2. Buy popcorn, candy corn and four bags of colored candy.
3. Write four house names on four jars.
4. Start the movie.

Everything else is extra.

See you next time

I'll send a short note like this when I have something seasonal worth trying. Next up is our December plan for the Cold Moon (the full moon this year falls right before Christmas Eve, and I have opinions about hot chocolate).
