Choosing the right 1+1 tubular flat and cording head embroidery machine can help you create high-quality embroidery designs efficiently and effectively. Here are some tips to help you choose the right one:

1. Number of heads: Consider the number of embroidery heads you need. A machine with 1+1 heads means it has one flat head and one cording head, which can increase the versatility of the machine.

2. Needle count: Check the needle count of the machine. A higher needle count can provide more flexibility and precision in creating intricate embroidery designs.

3. Embroidery area: Consider the size of the embroidery area. Look for a machine with an embroidery area that can accommodate the size of the designs you plan to create.
   

4. Speed: Check the speed of the machine. A faster machine can increase productivity and efficiency, but make sure the speed is adjustable to accommodate different types of designs and fabrics.

5. Software compatibility: Consider the compatibility of the machine with embroidery software. Look for a machine that can work with the embroidery software you plan to use to create and edit designs.

6. Brand and price: Consider the brand and price of the machine. Look for a reputable brand that offers a good balance of quality and price.

7. Customer support: Check the customer support offered by the manufacturer. Look for a manufacturer that offers good customer support, including training and troubleshooting assistance.

Overall, choosing the right 1+1 tubular flat and cording head embroidery machine will depend on your specific needs and preferences. Consider these factors when choosing a machine to ensure that it provides the performance and convenience you need for your embroidery projects.
