While a majority of the standard accessories are in the accessory bag with your machine, the large spool cap, 1 bobbin and the buttonhole foot are located on the machine itself.
These accessories are generally located in the following locations on your new sewing machine:
Buttonhole Foot:
The Buttonhole Foot is located in the removable front accessory tray
Large Spool Cap:
On model where the Large Spool Cap is a standard Accessory and it is not in the Accessory Bag, it is typically found on the Spool Sleeve at the top of the machine. To see if this is a standard accessory for your machine, please refer to your instruction manual.
Bobbin:
While there are several bobbins located in the Accessory Bag, if one is missing, please check the bobbin case.
