How to Sew a Hot Water Bottle Cover: Step-by-Step
Ready to start sewing? We’ll go through each step together. Just take your time and have fun with it.
Step 1: Prepare Your Pattern and Fabric
First, get your pattern ready. If you printed it, make sure you tape the pages together correctly. Once your pattern is assembled, carefully cut out the paper pieces. You should have one front piece and two back pieces (a top and a bottom).
Lay your outer fabric flat and place the pattern pieces on top. Cut one of each piece from your outer fabric. Then, do the same thing with your lining fabric. When you’re done, you will have six pieces of fabric in total: three for the outside and three for the lining.
Step 2: Sew the Back Pieces
Let’s start with the two back sections. Take the top back piece and its matching lining piece. Place them with the “good” sides of the fabric facing each other. Pin them along the single long, straight edge.
Now, sew along that straight edge with a 1.5 cm (or 5/8 inch) seam allowance. A seam allowance is simply the distance from the edge of the fabric to your stitch line.
Repeat this exact same step for the bottom back piece and its lining.
Next, open up the pieces you just sewed and press the seam open with your iron. Then, fold the lining to the back and give it another good press. To keep the lining from peeking out, you can do a quick “understitch.” This is just a line of stitches on the lining side, very close to the seam you just made. It helps everything lay flat and look neat.
Step 3: Assemble the Cover
This is the fun part where it all comes together! Lay your front outer piece on your table with the good side facing up. If you are using a fuzzy fabric for the lining, you can place the front lining piece underneath it now.
Next, take your finished top back piece. Place it on top of the front piece, with the good sides touching. The raw, curved edges should line up perfectly.
Then, take your finished bottom back piece and place it on top of the other layers, again with the good side touching the fabric below it. The two back pieces will overlap in the middle. This overlap creates the opening for the bottle. Pin everything securely in place all the way around the cover.
Step 4: Stitch It All Together
With everything pinned, it’s time to sew. Starting on one of the straight sides, stitch all the way around the entire cover. Use that same 1.5 cm (5/8 inch) seam allowance.
Take your time going around the curves. If you need to, you can stop with the needle down in the fabric, lift the presser foot, and pivot the fabric slightly. This will help you get a nice, smooth curve.
Step 5: Finishing Touches for a Professional Look
You’re almost done! Before you turn your cover right side out, we need to do a couple of things to make it look great.
First, trim the seam allowance down to about half its size. This removes extra bulk and helps the cover lay flat. Be careful not to cut your stitches! You can also clip small notches into the curved parts of the seam allowance.
To prevent the fabric from fraying inside, finish the raw edge with a zigzag stitch on your sewing machine. Go all the way around the inside edge.
Finally, turn your new hot water bottle cover the right way out through the opening in the back. Gently push out all the corners and curves. Give it one last good press with your iron, and you are finished!
FAQs
What is the best fabric for a hot water bottle cover?
Soft fabrics are a great choice. Try using flannel, fleece, or corduroy. Quilting cotton also works very well. You should avoid thin or slippery materials.
Can I make this cover without a lining?
Yes, you can make it without a lining. This works best with a thick outer fabric. A thick fleece or wool would be perfect. The lining just adds extra softness and heat protection.
How should I wash my new cover?
You should check your fabric’s care instructions. Most cotton or flannel covers are machine washable. Use a gentle cycle with cool water. Let it air dry to prevent shrinking.
Do I need a special sewing machine needle for this?
A universal needle is perfect for this project. Use a size 80/12 or 90/14. This size works for most medium-weight fabrics. Always start with a fresh, sharp needle for the best results.
