Large Baby Block Rattle Sewing Tutorial - Beginners Sewing Projects

Adding ribbon tags to the seams of the block gives the cube more texture and provides something for baby to grasp. This baby block tutorial is in celebration of 80 years of Poly-fil with Fairfield World. Poly-fil is a premium polyester filling that is washable, hypoallergenic and made from recycled materials. Gather up your materials below and let’s get started!


Choose soft fabrics like flannel or flannelette that are gentle for baby’s skin. One way to get a variety of coordinating prints at an affordable price is to up-cycle a collection of receiving blankets. Alternatively, you can purchase flannel fabric by the yard and make a super easy flannel baby blanket to make the block rattle toy. Interfacing is used to give the block more structure, and it is stuffed with Poly-fil.

Jingle bells are used to give the rattle a gentle sound when the block is moved. Rattle inserts can be used to give the toy a sound of chimes, if you prefer. Grab some ribbon in varying colors and textures if you would like to insert tags into the block.


Before you begin this Large Baby Block Rattle Sewing Tutorial, I always like to prepare my fabric by washing, drying and ironing it. This process acts as a preshrink so that your stitches don’t pull out later and ironing your fabric makes it easier to cut!

Step 1 – Cut Fabric

Use the rotary cutter, cutting mat and acrylic ruler to cut your fabric into 10″ squares. You will need 6 squares total. They can all be cut from the same fabric or mixed and matched.

Step 2 – Cut Interfacing

Next, cut the interfacing into 6 squares measuring 9.5″ each.

Step 3 – Iron Interfacing

Now on this large baby block rattle sewing tutorial, we will iron the interfacing to our fabric. Follow your interfacing instructions to fuse it to the center of each fabric square, on the wrong side. Typically, you will cover the interfacing with a damp cloth. Then press with a steam iron for 15 seconds. Lift and repeat until the interfacing is fused to the fabric.

Step 4 – Continue Interfacing

Continue pressing interfacing onto each fabric square until all six are completed.

Step 5 – Layout

Next on this large baby block rattle sewing tutorial, lay the squares out on a flat surface with three across and four down, meeting in the center like a cross. If you are using multiple fabrics, make sure you like how they are placed. The square in the center will become the bottom of the block, and the square at the bottom will become the top.

Step 6 – Add Ribbon Tags

To add ribbon tags to your large baby block rattle (optional), cut 3″ lengths of ribbon. Fold the ribbon into a loop, and clip it to the right side of the center fabric square with the loop facing toward the middle.

Step 7 – Assembly

Fold a square adjacent to the center square onto the center square with right sides together. Clip the side where the squares touch in the layout.

Step 8 – Sew

Now on this large baby block rattle sewing tutorial, it’s time to put it all together! To sew the squares together, begin stitching 1/4″ from the corner with a 1/4″ seam allowance. Sew down the side, stop 1/4″ before reaching the next corner.

Step 9 – Open and Press

Open the seam you just created to reveal the ribbon tags. Press the seam open.

Step 10 – Build the Block

Next, repeat steps 6-9 for the block on the opposite side of the center block.

Step 11

At this point in this large baby block rattle tutorial, you should have three squares across with ribbon tags in between them, if you choose.

Step 12

Continue building the baby block rattle by adding the squares below center.

Step 13

Sew the bottom two squares together where they meet. Then fold the squares up to meet the center squares with right sides together.

Step 14

Remember to start and stop sewing 1/4″ from every edge!

Step 15

Continue to add loops of ribbon between the squares as desired.

Step 16

Now on this large baby block rattle sewing tutorial, fold the top square onto the center square with right sides together and sew.

Step 17

Your cross layout of squares for the large baby block rattle should all be sewn together now.

Step 18

To make our large baby block rattle take shape, start by folding each square up to the meet the closest edge of the center square, right sides together. Do this one at a time and sew, still starting and stopping 1/4″ from each edge.

Step 19

Fold the remaining square over the top of the block and clip it in place.

Step 20

Sew around the square leaving a 3″ opening on one side.

Step 21 – Trim Corners

Next on this large baby block rattle sewing tutorial, trim each corner to reduce bulk in the seams. Make sure you do not cut through your stitches.

Step 22 – Turning

Reach inside the block, and pull it through the opening to turn it right side out.

Step 23

Use a turning tool to gentle press out the corners. Take care not to press through the fabric.

Step 24 – Stuff

Next on this large baby block rattle sewing tutorial, it is time to the stuff the block with Poly-fil. Press the filling into each corner with the tool provided. Then stuff the middle.

Step 25 – Add Sound

If you would like your baby block to rattle, add a handful of bells in the center of the block. Then continue filling the block with Poly-fil.

Keep in mind that surrounding the bells with Poly-fil will muffle the sound. Stop and test the sound to adjust the number of bells you prefer.

Step 26 – Closing

For the final step in this large baby block rattle sewing tutorial, we just need to close the opening. Once the block is stuffed to your liking, use a needle and thread to hand stitch the opening closed with an invisible stitch or ladder stitch.

And that’s it! Your large baby block rattle is complete!


The baby block can be spot cleaned or laundered as needed. The fabric and Poly-fil are both washable.
