When you have to increase more than 2 stitches at a border, for sleeves or underarm , you can increase with the cable cast-on as follows:
1. Insert Right needle between the 1st and 2nd st | 2. Wrap the working yarn around needle |
3. Pull a loop through the 2 st | 4. Transfer the new st on Left needle |
5. One new st increased | 6. Start again from 1 to 5 for the desired number of st. |
7. New stitches increased | 8. Knit these new stitches |
Hope this will be helpful
Happy knitting
