Learn how to use the Brother Circular Attachment Bundle (SACIRC1) to sew perfect circles from 30mm to 130mm with straight, zigzag, and decorative stitches.
Quick Answer
To sew precise circles with your Brother machine, attach the Brother Circular Attachment Bundle (SACIRC1), set the radius between 30mm and 130mm, and let the fabric pivot automatically as you guide the stitch.
Why the SACIRC1 Makes Circle Sewing Easier
Sewing perfect circles by hand is tricky—fabric shifts, curves wobble, and measurements get lost. The Brother Circular Attachment Bundle automates the pivoting, so your fabric rotates smoothly under the needle. That means consistent, accurate circles every time, whether you're adding a decorative touch to a quilt or creating custom embellishments.
The attachment works with straight stitching, zigzag, and decorative stitches, giving you creative flexibility beyond simple outlines. It's also easy to set up and use, so you can focus on the project rather than wrestling with the fabric.
What You Can Create
With radii from 30mm to 130mm, you can sew circles for appliqué, yo-yos, doilies, or even custom embroidery motifs. The bundle also includes a Braiding Foot with an adjustable guide, which lets you add cords, ribbons, or braiding up to 5mm thick—hands-free after setup. This opens up even more decorative possibilities for your sewing projects.
Step-by-Step Guide to Using the Brother Circular Attachment
- Set up your machine: Remove the standard presser foot and attach the circular attachment base according to your Brother machine's manual. Ensure the attachment is securely clicked into place. Check that the attachment is firmly locked before threading the fabric.
- Choose your radius: Select the desired circle radius between 30mm and 130mm. Adjust the pivot point on the attachment to match your measurement. Double-check the radius with a ruler. A misaligned pivot point will produce an oval, not a circle.
- Position your fabric: Place your fabric under the needle, with the pivot pin inserted at the center of your desired circle. Make sure the fabric lies flat and the pin is firmly in the fabric. If the pin isn't secure, the fabric may slip and ruin the circle.
- Select your stitch: Choose straight stitch, zigzag, or a decorative stitch on your machine. Adjust stitch length and width as needed for your project. Test on a scrap piece first to ensure the stitch looks right.
- Sew the circle: Start sewing slowly, guiding the fabric gently as the attachment pivots it automatically. Keep your hands clear of the needle and let the attachment do the work. Avoid pulling or pushing the fabric; let the pivot mechanism rotate it smoothly.
- Finish and remove: When you reach the starting point, stop sewing and raise the needle. Carefully remove the fabric from the pivot pin, then trim any loose threads. If your circle has a gap, you can sew a few stitches in place to close it.
