Is it easy to operate for someone who has never used a sewing machine before? The handheld sewing machine does not have complicated pedals or settings. Just install the battery/ USB cable (select the power button), thread the sewing thread properly, and start sewing. The product manual has detailed operating instructions. How thick fabrics can the handheld sewing machine handle? Can it sew denim, corduroy etc.? The sewing machine can easily sew fabrics like cotton, silk, thin linen (≤1.5mm thick). But its single-thread design limits sewing on extremely thick materials (e.g., thick denim, corduroy, blanket, leather). How is the sewing machine powered? The handheld sewing machine can be powered by AA batteries (not rechargeable) and a power adapter. Install the batteries in the specified order and don't forget to adjust the power supply mode button before use. Will the stitches be neat and durable? Before using, test the sewing thread tightness and adjust the tension knob to prevent thread skipping, breakage or loose stitches. Remember to tie a knot at the thread end after sewing, or the stitch will be loose. Is this single-thread hand-held sewing machine easy to carry? I want to take it with me when traveling. Very convenient to carry! It is small and light, can be easily put into luggage or handbags, does not occupy space, does not gain much weight, can be taken at any time when traveling or outdoor manual activities, and is a caring assistant for travel
