Do i cast on stitches everytime after the R1 instruction.
Getting my head round the next bit!

Hi, After working R1 you cast on the correct amount of sts for the size you are making and then work R2. You only cast on the one time. You repeat R1& R2 the correct amount of times for the size you are making which will leave you with the stitch count for each ‘panel’ at the end ie. front,sleeve,back & sleeve stitch totals.
Hope this helps, best of luck,
