How to Carve Your Address into a Pumpkin with a Hot Knife

How to carve a foam pumpkin with your house address using a hot knife that you can place on your front steps or porch on Halloween night.

I love decorating with pumpkins; they are one of my favorite things. Their bright orange color is so warm and cheery. I usually don’t carve pumpkins until the end of October to greet the Trick-or-Treaters for Halloween, but this year, I received a few foam pumpkins from Michaels to personalize. Since they are foam pumpkins – they will last forever.

Last week, I showed you how I carved one of the pumpkins into a Pumpkin Purse. I also carved one into a Pumpkin Candy Jar. Today I want to show you how I carved the largest pumpkin with a hot knife.

I carved my house number into the foam pumpkin and then placed it on a bed of leaves on an urn. It is a nice way to decorate the outside of your house for the season that you will be able to reuse for years.

You can’t place a lit candle in foam pumpkins, but you can use the battery operated tea-lights or candles to add a night time glow.

How to Carve a House Address Number Into a Pumpkin With a Hot Knife

supplies needed:

To find free fonts to use for the numbers, check out my favorite free fonts: Free Fonts | Free Fonts 2 | Free Fonts 3

Foam Pumpkin
Hot Knife – Sold at craft stores or here
Computer printout of your address numbers. I fit my numbers into a 6” wide and 4 1/4” tall square. I used the font Georgia
Needle
Tape

Create your address on your word processor and print out. Center the number printout on the front of the pumpkin. Secure on pumpkin with tape.

2. Use the tip of a needle to punch holes right along the outer edges of the numbers.

3. Remove the paper to reveal the outline of each number.

4. Plug in hot knife and let it get hot. It will take a few minutes. Once heated, place the tip of the hot knife along one number to start cutting following the dotted lines.

This photo shows the angle the hot knife goes into the pumpkin.

Pumpkin Carving With a Hot Knife Tips:

The hot knife comes with a metal stand. Use masking tape to secure the stand to a protected work surface. (I tape it to a rubber mat I have on my work table.) This way it won’t move when you place the hot hot knife to rest on it.

Carefully screw in the knife blade. Do not touch the knife blade or metal parts when the knife it heated. It gets hot.

Do not apply excess pressure to the hot knife point. Let the heat from the tool do the cutting.

The tight curves in a design are the hardest to cut. If you have a piece of foam board, practice on that before you start to carve your pumpkin.

Use long fluid motions for straight lines.
Draw the knife out so only the tip is in the pumpkin as you go around curved areas.
Bring the blade all the way out and place back in to cut around corners.
Once numbers or your design is cut out, use a nail file or piece of sandpaper to smooth the cut edges on the pumpkin.

Do you need to use any kind of sealant on them for outdoor use? Or test it like patio furniture and bring it in when it’s raining?

  Hi Kaitlynn – I didn’t add a sealer on my pumpkin. I used it for 3 years in the fall and I never saw any damage inside or outside the pumpkin. I left it out in the rain and autumn weather and brought it back in after Thanksgiving. I moved from the house a few years ago and left it with the house as the new owner wanted it since I would no longer need it. It could still be in use. If you want to seal yours, it can’t hurt, but I think since it is polyfoam, it is pretty durable.

Can you tell me how you secured the pumpkin to the urn so it didn’t get blown away… I tried using a piece of floral wire in mine cause I’m sitting it on wood was going to put holes in the bottom… but the wire isn’t sturdy enough to push thru and stay curved to come thru the other side..

  Hi Chelsea – Depending on how large the openings you cut are, you could fill the pumpkin with sand or small stones (up to the first cut so they don’t show) to weigh it down. Pour the sand through the cuts.

I love the way your pumpkin looks with your house number! I just picked up two 9″ pumpkins (and orange and black one) from Michaels today for $5.99, and also a hot knife, which I’ve never used before, so your tutorial is very helpful! Thank you for sharing!

Thank you for telling me about the prices. I could not for the life of me find one of those foam pumpkins. I must be looking in the wrong places. I guess I better be satisfied with the two I got years ago that are smaller, hard plastic for carrying candy and have the black faces already painted on them. I usually just put some rocks in those and set them outside my front door. I have been spending money the past few months and not saved any, so I need to behave myself now. lol. I will be very sad if I lose my home for not paying the property taxes, so save I must.

What would you substitute for a hot knife? I love the project, but don’t want to buy one.

Thanks!

  Hi Kitty – You could use the little pumpkin carving knives with the orange handles they sell or an X-Acto knife – which is a nice craft knife that you can change the blades on. They sell many different style of blades – long, thin, curved etc. You can find any of these knives at your craft store.

Oh I love this one. Your numbers show up black….. did you put some black fabric or paper behind them for the photo?

Do you remember how much this large pumpkin cost and the hot knife?

  Hi Sheryl – I didn’t put anything behind the numbers. I chose a thinner font so that you would not see into the pumpkin. Larger cuts would expose the interior more and you would see the light interior. The large pumpkin is around $20. If you use a Michaels coupons you can get it at least 40% off. The hot knife runs around $20

Good idea on the foam pumpkin and battery operated candles! I always see great carving ideas but was never interested in putting that much effort into a pumpkin that would start rotting in a matter of days ;)
