Because the threads must passthrough several thread guides at high speeds, they must be of uniform thickness and high strengthwith a minimum amount of linting.Goodquality cotton or cottoncovered polyester threads sew well, though they produce more lint, creating the need to clean the machine more frequently. Poor grades of thread can result in frequentfraying, breaking and unbalanced stitches.Threads of other fiber contents and weights may be used, depending on their strength and thickness.Testing will help you determine how easily they can pass through the thread guides, thread slots, needles and loopers.Important Note: For maximum performance of the Baby Lock, it is recommended to use "100% polyesterlong fiber thread". Recommended brands are MaxiLock and Metrosene. This thread also performs best when used with many decorative threads for sewing specialty decorative techniques.Optional Accessories(CHAIN/COVER STITCH OPTIONAL ACCESSORIES)Belt Loop Folder (3/4", 19mm) ROB0421S12AE (BLE8S12)Belt Loop Folder (11/2", 38mm) ROB0421S11AE (BLE8S11)Single Fold Bias Binder (28mm) ROB0421S04AE (BLE8S4)Single Fold Bias Binder (40mm) ROB0421S05AE (BLE8S5)Double Fold Bias Binder (11/8", 28mm) ROB0421S03AE (BLE8S3)Double Fold Bias Binder (13/8), 36mm) ROB0421S02AE (BLE8S2)Elastic Gatherer Bracket U.S.A. only (BLE8GG)Elastic Guide for Gatherer Bracket (1/4", 7.5mm) U.S.A. only (BLE8EG7)Elastic Guide for Gatherer Bracket (3/8", 10mm) U.S.A. only (BLE8EG10)Elastic Guide for Gatherer Bracket (1/2", 13mm) U.S.A. only (BLE8EG13)Fabric Guide ROB0420S01AE (BLE8FG)Plain Hemmer (1/4", 7.5mm) ROB0421S07AE (BLE8S7)Plain Hemmer (1/2", 13mm) ROB0421S06AE (BLE8S6)Single Downturn Feller (1/4", 7.5mm) ROB0421S10AE (BLE8S10)Single Downturn Feller (5/8", 16mm) ROB0421S08AE (BLE8S8)Single Downturn Feller (1", 25mm) ROB0421S09AE (BLE8S9)Knit/Woven Double Fold Bias Binder (8mm) ROD13408E (BLCSDFBB8)Knit/Woven Double Fold Bias Binder (10mm) ROD13410E (BLCSDFBB10)Knit/Woven Double Fold Bias Binder (15mm) ROD13415E (BLCSDFBB15)Clear Foot B5002K03AE (BLCSCLF)Pintuck Foot w/2 Guides ROB500206BCE (BLCSPTF)NOTE:・Use the front two Attachment Screw Holes for the Knit / Woven Double Fold Bias Binder.・Use the back two Attachment Screw Holes with the Accessory Adapter for the OptionalAccessories.These optional accessories are available at your Baby Lock retailer.
