Jelly Roll Rug

The Jelly Roll Rug (originally designed by Roma Lambson) is a incredibly popular, cozy, and durable project. It transforms one standard Jelly Roll (a pre-cut bundle of forty $2.5″ \times \text{WOF}$ strips) and 2.5-inch wide batting strips into a beautiful, coiled accent rug.

Here is the complete, comprehensive master guide in English to making your own Jelly Roll Rug.

1. Materials & Supplies Checklist

• 1 Fabric Jelly Roll: Contains (40) $2.5″ \times 42″$ strips.

• Batting Strips: You will need approximately 50 yards of $2.5″$-wide batting. You can buy pre-cut rolls (like Bosal Duet-Fuse II or Katahdin On-a-Roll) or cut your own from leftover quality cotton batting.

• Thread: At least 1,200 yards of 50wt cotton thread. Match it to your fabrics or use a neutral color (cream/grey), as it will be highly visible in the zigzag stitching.

• Sewing Machine Needles: JEANS/DENIM size 90/14 or 100/16. You will be sewing through multiple thick layers of fabric and batting; regular piecing needles will bend or snap.

• Optional but highly recommended: A sewing machine extension table (to support the weight of the rug) and Mary Ellen’s Best Press (or starch).

2. Step-by-Step Assembly Instructions

Part 1: Making the Continuous Fabric Strip

Instead of sewing the strips end-to-end with straight seams (which creates bulk), you will join them using mitered (diagonal) seams.

1. Arrange Your Strips: Unroll your Jelly Roll and arrange the strips in the order you want them to appear, starting from the center of the rug moving outward.

2. Join the Strips:

   • Take the first strip and place it face up. Take the second strip and place it face down at a right angle ($90^\circ$) over the end of the first strip, creating an “L” shape.

   • Sew a diagonal line from the top-left corner of the intersection to the bottom-right corner.

   • Trim the excess corner fabric leaving a $1/4″$ seam allowance. Open the strip and press the seam open flat.

3. Repeat this process for all 40 strips until you have one massive, continuous fabric strip that is roughly 45 yards long. Roll it loosely into a big ball or pile it carefully into a laundry basket to keep it untangled.

Part 2: Wrapping the Batting (Creating the “Rope”)

Now you will wrap the batting inside the fabric strip to create a long, padded noodle.

1. Lay your fabric strip wrong side up on your ironing board.

2. Lay your $2.5″$-wide batting strip directly down the center of the fabric.

3. Fold the Edges:

   • Fold both raw outer edges of the fabric strip inward so they meet exactly in the center over the batting.

   • Then, fold the entire strip in half again lengthwise, enclosing all raw edges inside. Your strip will now be approximately $5/8″$ wide.

4. Press and Secure: Press this folded sandwich flat with starch. Use clips (like Clover Wonder Clips) to hold several yards of the folded strip together at a time.

5. Sew the Strip Closed: Sew a straight stitch down the open, folded edge of the strip using a standard $1/4″$ seam or less. Do this for the entire 45 yards. You will end up with one enormous ball of covered batting rope.

Part 3: Sewing the Rug (The Coiling Process)

This is where the magic happens. You will stitch the long rope to itself using a wide zigzag stitch to form an oval rug.

1. The Critical First Turn (The Center)

The length of your initial center loop dictates the final shape of your oval.

• Measure exactly 13 inches from the raw end of your rope.

• Fold the rope back onto itself at that 13-inch mark so that the long remainder of the rope is running down the right side of your starting tail.

2. Setting Up the Machine

• Select a Zigzag Stitch on your sewing machine.

• Set the Stitch Width to $5.0\text{mm}$ – $5.5\text{mm}$ and the Stitch Length to $2.5\text{mm}$ – $3.0\text{mm}$. You want a wide, sturdy stitch that securely grabs both ropes side-by-side.

3. Stitching the Oval

1. Begin sewing down the center of the two touching pieces of rope. The zigzag stitch must catch the left rope on its left swing and the right rope on its right swing.

2. When you reach the end of the 13-inch strip, you must turn the corner to wrap the long rope around the end.

3. Crucial Flatness Secret: When turning corners, NEVER pull or stretch the outer rope. Pushing or stretching the outer strip as it curves will cause your rug to warp and bowl up like a basket. Instead, let the machine feed the outer rope naturally, slightly forcing extra fabric into the turn (“crowding the turn”).

4. Keep the entire growing rug completely flat on your extension table or a flat table surface. If the rug hangs off the edge of your machine, its own weight will pull at the needle and distort the flat shape.

5. Continue circling counter-clockwise, zigzagging the coils together.

4. Finishing the Edge

1. When you reach the very end of your long rope, trim the batting out of the last 2 inches to reduce bulk.

2. Tuck the raw fabric edges inside itself to create a clean finish, tuck it tight against the previous loop, and heavy-stitch/backstitch it securely in place.

💡 The “Wavy Rug” Troubleshooting Guide

If your rug starts looking wavy or bowing upward like a bowl while sewing, stop immediately. Do not try to fix it later; it will not press out.

• If it’s waving (too much fabric): You pushed too much fabric into the curves. Unpick a couple of rows and stitch them with less slack.

• If it’s bowling (cupping upward like a dish): You pulled the outer rope too tight around the turns. Unpick those rows and let the outer rope feed completely loosely around the curves.
