Circles- Sewing Machine Attachment vs. Acrylic Table
On my bucket list this year is a quilt with circles. I have several patterns in mind. I completed the simple one in the photo (hope it attached) using the "thumb tack tapped to the bed of the machine" technique. It certainly worked, but had its disadvantages that all circles needed to be completed at once while the thumbtack was in position and very difficult to make any adjustments after the fact. I am considering a circle sewing machine attachment for my Brother machine - about $60-90 or purchasing an acrylic table extender with the holes and the table circle tool - about $150. Does anyone have experience with both the sewing machine circular attachments and the acrylic table extensions with their own circular sewing tools for completing circles? Which do you prefer and why? Thank you for your assistance.
