How to Make A T-Shirt Quilt: Adding Sashing TITLE

This is the second blog post in our t-shirt quilt series. I’ll note, it is a photo heavy tutorial. If you prefer videos, I’ve also included my YouTube video tutorial at the end of the post.

Last time we prepped our t-shirts with interfacing to make it stiff and non-stretchy.

When you are considering piecing your quilt top, remember that you need to have your shirts laid out in the order that you want them placed when your quilt is complete. A good tip is to tell a story with how you lay out the t-shirts.

Some of the t-shirts that I am using on this is Alpha Omega sorority quilt had a front side and a backside with designs and text that my client wanted me to use. Considering this, I chose not to put them right beside each other because I wanted to have a variety of colorful shirts on the quilt. I did, however, put them diagonal to each other so they were easy to read but still had a design variety. In another post in this series you will see how it’s actually laid out.

After you have determined the order of your quilts, we then want add a 2.5″ sashing to the inner edges of the t-shirt blocks.

Ensure that the right sides of the fabric on both your shirt and the shirt are facing each other.

Line it up along the edge.

Once it is placed how you want it, you’re going to sew using a quarter inch seam.

You’re going to go all the way to the end of the shirt block and then you’re going to trim it.

Continue assembling the sashing only on the inside squares. Do not add sashing to the outer edges of the row.

Now that your rows are assembled we are going to add a long strip the row

Only the top row will have you adding long strips of sashing to it. The rest will just be the bottom. Remember, put right sides together and use a ¼ inch seam.

For subsequent rows you will only have sashing on the bottom. If you do the top and bottom to all of the rows you will have doubled up the sashing when it is pieced together and we don’t want that.

Remember to not add fabric to the outer edges yet.

Your sashing is done on the inside and now on the top and bottom of each row. Time to sew the rows together!

As there is material between the rows, you have to be careful to line up the shirts so they look straight. To do this, place one row on top of the other so you can see the t-shirts on both rows.

You can use a ruler or a straight edge to ensure it is lined up. Get your pins and mark on the sashing where the t-shirt on the previous row sits. As you sew, ensure that the t-shirt edges line up with these pins.

Now that you have pinned or marked, you are ready to sew the rows together with the fabric right sides together. Be sure that before you sew that your t-shirts are in the correct direction.



Now you should have a nicely gridded quilt top.

Snowman Tree Skirt

As promised, today I am showing another item I made for the Christmas season – a tree skirt in the Snowman theme! When I did the craft shows earlier this month, I was intrigued that several people approached me asking for anything “snowman” as they collected them. I did have one quilted version of this but then decided to try a few unquilted just for fun. I like the traditional circular shape of these. Visit my Etsy shop to see if they are still available!

9 Simple Steps to Organize Your Craft Room

UPDATED: July 12, 2019 In my head, I see an organized craft room that houses all my supplies. Yarn is stacked neatly in shelves and buttons are organized in colour-specific mason jars so I can see my stock in one quick glance. My eyes tell me that my reality is far from this dream – especially when I’m creating a new collection, the yarn and papers creep out of my studio into my living quarters because sometimes I just need to test a pattern in front of a good Hallmark movie or British TV series. Rubbermaid bins are filled with
