Bargello Quilt Tutorial: Jenny Doan's Stunning Jelly Roll Wave Quilt

🧵 1 jelly roll (2½-inch strips) — Jenny used Lush Lagoon by Kona Cotton for Robert Kaufman. You need a roll with a clear gradient from dark to light — solids work best for the classic Bargello look. Shop jelly rolls.

🧵 ¾ yard of contrasting fabric — this creates the accent stripe that runs through the center of the wave pattern. Choose something that pops against your gradient colors. Shop fabric.

📏 ¾ yard for border — a simple border to frame the finished quilt

✂️ Rotary cutter, long ruler & cutting mat — you'll be cutting through multiple layers, so a sharp blade is essential. Shop rotary cutters.

📌 Pins — for keeping seams aligned when joining columns. Shop pins & clips.

Step 1: Sort Your Strips by Color Gradient

Unroll your jelly roll and sort the strips into a gradient from dark to light — you should end up with roughly 12 color groupings. Within each group, you need three strips of each color. If a color has four strips, set the extra aside for binding.

This sorting step is the foundation of your entire Bargello. Take your time getting the gradient right — lay strips out on a table or the floor and stand back to check that the colors transition smoothly from dark to light.

Step 2: Sew Three Strip Sets

You're going to create three identical strip sets. For each set, take one strip from each color group (so one strip from each of your ~12 colors) and sew them together in gradient order — dark to light — with ¼-inch seams. Sew up one side, down the other, alternating direction to prevent curving.

When you're done, you'll have three long panel-like strip sets, each containing one strip of every color in your gradient. They should all be arranged in the same order.

Step 3: Add the Contrasting Center Strip

Take your ¾ yard of contrasting fabric and cut a 9-inch wide strip across the width. This is your accent — the bold stripe that will create the focal point of the wave pattern.

For two of your strip sets, sew this 9-inch contrasting strip to the lightest color at the end of the gradient. For the third strip set, cut it in half (to create two shorter strip sets that will add width to your quilt). The contrasting strip should always join to the lightest color.

Step 4: Form Tubes

Here's where the magic begins. Take each of your two main strip sets (with the contrasting strip attached) and sew the top edge to the bottom edge to form a tube. You're connecting the darkest strip to the other side of the contrasting strip, creating a continuous loop of graduated color.

Make sure the fabrics are right sides together and that you don't twist the tube. When you're done, you'll have a fabric tube where every color flows into the next in a continuous gradient circle.

Step 5: Cut the Tubes into Columns

Flatten each tube and cut it crosswise into columns of varying widths. This is what creates the wave effect. Jenny recommends cutting columns in widths like: 1", 1½", 2", 2½", 3", 3½" — and then reversing back: 3", 2½", 2", 1½", 1". The varying widths create the rising and falling wave pattern.

Each column is a ring of fabric that contains one piece of every color in your gradient. When you open the ring at different seams, you shift which color is on top — and that's how the wave forms.

Step 6: Open Rings and Arrange the Wave

Each ring (cut column) needs to be opened by unstitching one seam. Which seam you open determines where the color sequence starts for that column. By opening each successive column at a different seam, you shift the colors up or down — creating the wave.

Lay out your opened columns side by side on a design wall or flat surface. Adjust which seam you open on each column until you see the wave pattern emerge. The contrasting strip should flow in a smooth curve across the quilt.

Step 7: Press, Sew Columns Together, and Finish

Press each column with all seams going in the same direction (down). Then place columns right sides together and pin at every seam intersection — the seams should nest together since they're all pressed the same way.

Sew columns together with ¼-inch seams, working from one side of the quilt to the other. Add a border, layer with batting and backing, quilt, and bind. Stand back and prepare to be amazed.

🎨 Solids make the best Bargello: While patterned jelly rolls can work, solid fabrics (or near-solids like Kona Cotton) produce the crispest wave effect. The gradient needs to read clearly from a distance.

📏 Accurate seams are critical: Since you're sewing 12+ strips together, even a tiny seam variance multiplies across the strip set. Use a consistent ¼-inch seam throughout — check by measuring your strip set height.

✂️ Label your columns: Before moving your cut columns, number them with masking tape or sticky notes. It's easy to lose track of the order, and rearranging later is frustrating.

🔥 Press consistently: Press all seams in the same direction within each column. This ensures seams nest together perfectly when you join columns — which is essential for those clean color transitions.

🧵 Pin at every seam intersection: When joining columns, pin where every seam meets. The wave effect depends on precise alignment of colors across columns. Take your time here — it pays off in the finished quilt.
