Leveling off an uneven edge
Sloping edges, such as those at a shoulder or neck edge, can be leveled off with an extra pattern set in which the forward row is worked into each vertical st and the return row is worked as usual.
Pieces worked in Tunisian crochet are usually finished with a forward row of sl sts worked into the vertical sts.
Single st dec can be done by sk sts in the forward row or by working 2 vertical sts tog.
When dec several sts per side, work the right side in sl st for the required number of sts. On the left side dec by omitting the desired number of sts
Inc by 1 st on the vertical sts by casting on a new st on the cross ch between 2 vertical sts.
Inc by 1 st on the cross sts by casting on new st on the vertical sts. In both cases the return row is worked as usual.
When inc by several sts per side, work the desired number of ch sts onto the right side using these to work the new sts on the next forward row. The same principle applies as when casting on, sk the st nearest the hook at the beg of the forward row.
Sample with inc and dec at the sides
Ch 2, work 1 forward row ( =2 sts on the hook) and 1 return row. In the next forward row inc by 1 st on the cross ch between the 2 sts (= 3 sts on the hook). Work the return row as usual. Thereafter inc by 1 st on the cross ch aftger the first and before the last sts (edge sts) during the forwar rows, working the return rows in the usual way.
Sk the second and the next to last sts (vertical sts) on the forwar row and work return rows as usual.
