    The parallel glider is one of those tools that will surprise you with its usefulness! I reach for it every single time that I go to create calligraphy or hand lettering. In this article, I’ll show you three ways to use a parallel glider with a series of short video tutorials.

    How to Use a Parallel Glider (AKA a "Rolling Ruler")

    I’ve never been a math person, so my 2014 purchase of a parallel glider wasn’t exactly exciting. To me, the contraption had way too many numbers written on it — seemingly arbitrarily. When I went to draw guidelines for calligraphy, though, it was love at first gloriously parallel roll! Making guidelines suddenly wasn’t a tiresome and tedious task, and slant lines could be whipped up in a few quick swipes. Seven years later, I still use the same parallel glider regularly. Today, we’ll talk about how a parallel glider can make lettering life easier for you.

    What is a Parallel Glider?

    Circus Lettering Printable Exemplar + Video Tutorial | The Postman's Knock

    A parallel glider, also known as a rolling ruler, is a ruler that rolls up and down, making it easy to create parallel horizontal or vertical lines. It’s easy to find cheapie parallel gliders with plastic bases and ridged plastic wheels, but those have never worked for me. They don’t “glide” across a page like the Alvin parallel glider does.

    Drawing Guidelines With a Parallel Glider

    Calligraphy Guidelines | The Postman's Knock
    You can find this envelope guidelines template in the Marvelous Mail eBook.

    I remember my pre-rolling ruler days … and those days involved a lot of tedious time with a regular ruler. Now, I just line up the parallel glider with a guidelines sheet and draw guidelines as I move the ruler down. I made a tutorial video to show you exactly how to use your parallel glider to draw guidelines:

    You can download the free “Perfect Calligraphy Envelope Generator” featured in the video above by clicking here. For more information about making calligraphy guidelines, see the How to Make Calligraphy Guidelines tutorial.

    Making Slant Lines

    About Calligraphy Slant Lines | The Postman's Knock
    Slant lines are important for creating calligraphy that has a consistent stroke slant. They come in really handy for formal styles like the Janet, shown on this envelope!

    Not everyone uses slant lines, but they can really help when you want to write formal calligraphy. You’ll especially notice a difference if you’re creating elegant calligraphy styles that demand consistency. Here’s how the parallel glider makes slant line creation easy-peasy:

    You can download the free “Perfect Calligraphy Envelope Generator” featured in the video above by clicking here. For more information about making calligraphy slant lines, see the About Calligraphy Slant Lines article.

    Creating Neat + Clean Hand Lettering

    "George Style" Printable Hand-Lettering Exemplar | The Postman's Knock
    A parallel glider makes it much easier to create geometric hand lettering styles like the George.

    While you don’t have to have a rolling ruler for hand lettering, it can make a big difference for certain styles. In the video below, I’ll show you how I use a parallel glider to create George Style Lettering:

    If you like the hand lettering style in the video above, you can learn how to make it with this worksheet. (George Style lettering looks amazing on mail art!)

    A Word on Availability

    I have wanted to get my hands on a parallel glider wholesale order since I opened the Supplies Shop in 2019. Unfortunately, Alvin, the company that makes these rolling rulers, went out of business last year because of COVID. (As I understand it, they relied heavily on school orders, which weren’t placed last year due to schools being closed.)

    Calligraphy Guidelines | The Postman's Knock

    Another company purchased the rights to the Alvin name earlier this year, and they resumed manufacturing of these wonderful contraptions. The rulers are made at the same place in Poland to Alvin’s specifications … right down to the now-defunct alvinco.com URL written on the ruler. I am very happy to be able to offer you the same rolling ruler that I fell in love with years ago, and I know you’ll love it, too!

    GET A PARALLEL GLIDER HERE


    To be clear: having a rolling ruler won’t make or break your calligraphy creation. If it’s not in the budget, don’t worry about it! The same results can be achieved with a regular ruler, just with more fuss. But, if you’ve got a little bit of extra jingle in your pocket, I highly recommend snatching one of these up! Happy guideline creating, and we’ll reconvene this weekend with a fun holiday-themed tutorial.

    Warmly,

    So cool! I was wondering is there was a better and quicker way to draw lines without having to always do them by hand! Thank you!

    I used a rolling ruler for my holiday cards last year, but I only had the kind with a plastic roller. It rolled better if I placed a sheet of printer paper between my desk and the roller, and it did make lining cards easier. Maybe one day I’ll upgrade to an Alvin!

      Hahaha! I meant this for the wreath tutorial post! I’m keeping this one open on a tab in my browser in the hopes I unwrap one this weekend! What’s funny is I remember having one of these around the house when growing up, and reading this post reminded me of how easy it was to make parallel lines on paper with it.

    I’m usually a little lazy about the lines (it annoys me no end when they aren’t exact!) so this would probably really help. Combine it with a good eraser and my friends might be surprised how much more professional my envelopes look!

    I also purchased a rolling ruler because of this post and it is a wonderful help!! I’m one who can’t write or print in a straight line so I ALWAYS need lines! This tool is a necessity for making perfectly spaced lines. I use it for everything!

✨ One of the most beloved assignments from Lesso ✨ One of the most beloved assignments from Lesson 5 of Hand Lettering 101 was this playful project: design an artistic alphabet where no two letters look the same.

The idea? JUST PLAY. 🎨 I used watercolor and a paintbrush, but many students grabbed markers, pens, or anything colorful on hand. The results were incredible — @adriennelovesletters gave it her own flair, Isabel C. made it three times, and Laura M. created a stunning version too. (You can peek at more inside the TPK Premium Discord!)

If you’re ready to try this project yourself, you’ll find the Hand Lettering 101 eCourse waiting in the TPK Catalog. Just head to the link in my bio to be taken to the TPK website. 💌
