For a monochromatic quilt, choose T-shirts in the same color. If you prefer, use any shirts with sentimental value to make a vibrantly colored quilt. 16 T-shirts are needed to make a quilt that’s 4 blocks by 4 blocks [12 by 12 inches (30 cm × 30 cm)] in size.

The squares don’t need to be completely straight or smooth because you’ll be cutting them again later.

The fusible interfacing will make your T-shirts easier to work with since they’ll prevent the knit fabric from stretching or sagging a lot. Read and follow the manufacturer’s instructions for specific directions about fusing the interfacing. You’ll need to place the bumpy, fusible adhesive side so it faces the fabric.

If you want, make your squares larger or smaller. Keep in mind that you can adjust the overall size of the quilt too. Repeat this for each block so every T-shirt square is uniform in size.

If you’re using more blocks, you can make larger or longer rows.

Play around with moving the squares to determine what looks best to you. For a chronological quilt, place squares that have years on them from the earliest date to latest.

Work two blocks at a time so you can focus on one shared edge at a time.

If you have a walking foot for your sewing machine, attach it to make it easier to sew.

Ironing the seams flat will make it easier to quilt the material.

Keep the seams open as you sew across them. This will ensure that they stay flat.

For example, if you’re making a quilt that’s 4 blocks of 12 inches (30 cm) by 4, the blanket will be about 45 by 45 inches (110 cm × 110 cm), taking seam allowances into account. To add 2 inches (5. 1 cm), you’ll need a piece of backing that’s 52 by 52 inches (130 cm × 130 cm).

If you want a very thin quilt, leave out the batting entirely.

The batting will make the quilt fluffier and will insulate it. For a thicker quilt, add an extra layer of batting.

For the simplest way to quilt, sew it back and forth in straight lines.

You should only see a neatly trimmed T-shirt topping once you’ve trimmed off the excess from the edges.

For a 48 by 48 inches (120 cm × 120 cm) quilt, consider cutting the binding into 2 1⁄4 inches (5. 7 cm) strips.

Trim the end and fold it under the binding just before you finish sewing the last edge.
