My kids love to build. Last year I bought them some wooden blocks.
They like building more than they like sharing.
So I made more. They are getting them for Christmas, so alas, I cannot now show you a photo of glee filled toddlers happily playing together, cherubic smiles upon their faces as they work to build collaboratively.
I’ll show you that photo just as soon as it happens…
But I can show you this:
That’s a 100 piece set right there, folks.
Let’s talk about whether it’s worth it to make your own wooden blocks. Is it cost effective? Maybe. Some block sets are really, really pricey. Others, not so much. I calculated the cost if you didn’t have any of this wood on hand…then lost the paper I wrote the calculations on. But it pretty well came down to being a good deal for quality blocks, and something I would definitely do again.
Materials

I used hemlock and doug fir to make the blocks. You can use whatever, really. You’ll be able to make a set this large with:
1 – 1×2 @ 6′
3 – 2×2 @ 8′
1 – 1 1/4″ diameter closet rod @ 6′
Time
Can I get this done in time for Christmas?! Sure, just give yourself a couple of hours.
Tools
You can make these with just a miter saw and a table saw. You could also skip a couple things and use just the miter saw.
The Template
You know what I’m going to do? I’m going to give you a free template to make all of these patterns yourself. Seriously. No strings. I’m just that nice.

**UPDATE: Pattern number 10 (4.25″ 2×2) is incorrectly marked as a 45 degree angle. It should say 22.5 degrees. One way to make these cuts safer is to cut the angle, then chop it down to length. As always, remember to use all safety precautions when using saws.**
How to cut the wooden blocks
Okay, so you have the template, which tells you most of what you need to know. I’m going to level with you here. The number of blocks I made of each type is totally arbitrary. Switch it up if you like. Some blocks cut out super fast, some take more work. The notched blocks (#9) take some work. I made those by running them through the table saw repeatedly, then chiseling them out. If that sounds like a lot of work, skip that pattern. Your kid will never know.
The other blocks were made using the miter saw, with the exception of the final two patterns, #14 and #15. To make those I set the table saw on a 45 degree angle, then ran a long piece of 2×2 though. For extra safety I used a 6′ piece and only ran the first couple feet so my fingers were far away from the blade. After that I used the miter saw to chop the pieces, creating a larger and a smaller triangle for each cut because the table saw wasn’t set perfectly down the middle. Your’s probably won’t be, either, so you’ll end up with a large and a small triangle.
For the round blocks I used closet rods, which I had laying around the shop. These blocks are a terrific scrap wood project if you have things like that around. Check Restore as well and you can often snag a great deal.
Finishing
I sanded the edges of each piece using my stationery belt sander. Round all of those edges. The notched pieces you’ll have to hand sand a bit, as much as it pains me to say that. I hate hand sanding.
Finish the wooden blocks with food grade mineral oil. Because kids stick things in their mouths. And by things I mean everything.
Pile the whole lot of them in a big canvas bag, stick a bow on it, and enjoy the magic of your kids playing peacefully all day long. Or however it works out – results may vary.
As always, drop me a line if you have any questions, and happy building!
How di you cut the “arch” pieces (the ones with the semicircular opening in them)?
Thanks for the template!

Hi Eric. Sorry I missed this. I seem to recall using a forstner bit after clamping it down securely. As to the depth of the notch in the 2×2’s, yes, it is roughly half of the width so the pieces fit together smoothly.
Also, what is the depth of the notch in the 2×2? Is it just half the width of the 2×2 (or maybe slightly more so you could overlap to of them.
Thank Sarah
Made a set of these for a new dad friend of mine. It will be a while before the kid can play with them but it will keep the dad busy in the meantime!
Thanks for the plans
Eric
Thanks, Eric! I’m really glad to hear it!
The lumber we can easily buy isn’t exact demension. For example, the 2×2 was more like 1.75 x 1.75. Do your templates account for this odd measuring standard? Thanks!
Absolutely.
Thank you for the template.
Are the lengths of pieces equal to or whole multiples of the smallest length?
I want that so the blocks are more compatible with each other like a set I now have; so two smaller blocks stacks equal to height or length of the next larger block.
Is the diameter of the dowel pieces similar to the width of the blocks?
What is the length of pattern 11?
It is 4 1/2″ long
Hi Sarah,
What is most time-efficiant way of treating the blocks with mineral oil?
Thanks!
Keely
Mineral oil really only needs like 20 minutes to dry, and then can be wiped with a dry cloth. It’s a pretty quick process. 🙂
We have a new grandson born a week before Christmas in 2018. I’m hoping to make these for his next Christmas. Hey, I have 10 months, do you think I can do it?
This is so nice of you to have made templates for us!
What is the length of cut 11?
It is 4 1/2″ long.
Hi! Thank for your details above. They’re very helpful.
I have a quick question: I’m making blocks for my niece’s baby shower. I’d like the guests to decorate them for her. Should I finish them with mineral oil ahead of decorations? Is this possible?
Thanks!
I realize this is probably a bit late… Sorry about that. The mineral oil will likely keep whatever else you planned to use from adhering. But, depending on what you were thinking, you could always test it on a bit of scrap wood first. I hope it worked out for you!
