Pixelated Spectrum Placemats: A Sewing Tutorial

Pixelated Spectrum Placemats Tutorial

I LOVE these placemats!  At first glance they might look like a lot of work, but the construction is just simple patchwork.  They’re also less expensive that you might think, thanks to the use of just one pack of Michael Miller’s Cotton Couture charm squares, which makes it easy to have this gorgeous range of colors without the huge investment of multiple yardage cuts.  The charm pack contains 85 five inch squares in an absolutely beautiful spectrum of color.  (For more with Cotton Couture, check out this Spectrum baby quilt I made with one charm pack of Cotton Couture and two packs of white charm squares!  I think it’s my favorite quilt so far.)

To make six placemats, you’ll also need backing fabric (about a yard and a quarter), batting (crib size) and if you decide to use binding, one yard of fabric for that as well.  (Note: you may want to read the entire tutorial before beginning, because there are a couple alternative methods offered.  All seams are a quarter inch.)

First, separate your colors into six stacks, one for each placemat, with at least 14 charm squares in each.  Think about the way you want the colors to blend from one side of the placemat to the other when dividing them.  Then cut each charm square into four equal 2.5″ squares.

New Project

Line your squares up into nine rows of six squares each.  I added a square of white or cream for just a bit of “sparkle”, as if light were being reflected.  Be sure to blend the colors a bit, but not too much, so the hues shift as your eyes move across the placemat.  Pretty!

Sew each row of six together, taking care to keep them in order.  It helps to pretend the points of the pinked edges are the top of a flat edge, like this:

Then press the seams open.

Pin the rows together, carefully matching and pinning at the seams.

If you are new to piecing patchwork, you may want to take a look at Ayumi’s basket tutorial on Pink Penguin, a legend of internet sewing tutorials, which shows another method of lining up patchwork seams.  This is actually the way I learned to do patchwork and would work nicely for these placemats as well.  I chose the open seams method to make the seams just a little smoother and flatter since drinking glasses will be used on these, and I hoped to lessen the chance of any spills.

After finishing the tops, it’s time to quilt the placemats.  You have a couple choices here as well.  If you’d prefer to make the placemats without binding the edges, quilt only the top and batting together, then put the backing fabric face down on the top, pin in place and sew around the edges, leaving a few inches open to turn.  Carefully trim the corners close to the seam (but do NOT cut your stitches) so that the corners will be less bulky.  Then turn right side out and sew a finishing seam around the edges of the placemat.  (I apologize for not having photos of this method.  I like the way binding frames each placemat and went with that.)

If you are using binding, layer your backing fabric face down on the bottom, then stack batting on top of that and your finished placemat top face up on top.  Your backing fabric and batting should be slightly larger than the placemat top.

I use a quilting spray to keep everything in place while I sew, but you could also pin the layers to keep them from shifting.

Using a walking foot (which helps pull the layers of fabric evenly), stitch about a quarter inch from the horizontal seams.

And do the same for the vertical seams.

Trim closely around the placemat.

And now you’re ready to bind!  If you’ve never made or used binding before, I think the best tutorial is by Heather Bailey.    I like to cut my binding strips three inches wide.  The fabric I used is “Weave” in Coal from the Summersville collection by Lucie Summers for Moda.   I wanted to keep going with that grid vibe, but a solid black or something with a dark texture would be beautiful.

And enjoy!  Here’s a picture before washing:

And after they’ve been washed and dried, with all that crinkly, quilty goodness:

Finished size will be about 11.5″ x 17″.  If you make them, I’d love to see them — share a link to your pics or post, please!

  1. Love these! I just got an Accuquilt with a 2.5″ die, so I think I may try to make this from my scraps. I’m going to have to quilt more because I’m finding more things to do with scraps than with my actual stash.

  2. Awesome, I am new to quilting and fell in love with this. Is it possible you could send me a grid or something where each went or a picture of each one so I can match the colour squares, this will help me learn to cut squares, sew them, quilt lines and do binding. But the main thing the actual project is broken down into 6 projects.
    Brilliant placements.

    • Hi Sandra! Actually, it would be kind of impossible for me to chart out where each color went, because I don’t have a color card of these fabrics and the placemats now belong to my sister in law who lives over five hours’ drive from me. But part of the fun and creativity in this project is placing the colors the way YOU like them, so don’t get hung up on where the colors “should” go and put them wherever you like. You’re right, it is a great project for learning the process of patchwork, and you’ll end up with wonderful, useful works of art!
