On last round, stop one st shy of end of round, w&t
You should have just completed an increase round.
At this point, to extend the crotch a little further and add a bit more length to the back, we will work some additional short rows. Crotch increases will continue on either side of the gusset on right side rows.
Work as many short rows as you need to achieve a good fit. It is recommended that you periodically move your live sts to waste yarn and try the garment on. The front crotch gusset will go between your legs in front and meet with the back crotch gusset. Fit should be snug but comfortable when you complete this section.
Incs are worked on right side rows as follows:
*Work to center marker, l1l, SM, work to next marker, SM, l1r.* Work remainder of row as indicated.
You are no longer adding sts to the gusset. The back gusset needs to remain the same width as the front gusset. Increases are now happening outside the gusset.
Row 1: Work to one st before side marker, w&t.
Rows 2-7: Work to 5 sts before last w&t, remebering to work inc on even rows, w&t.
You should now be ready to begin a right side row. Knit to end of round, working incs as above and picking up all wraps along the way.
Legs
Each leg is made up of half the front and half the back, minus the gusset. Legs are each worked identically. Gusset is 8 [12, 12, 12, 12, 12, 16] sts wide. The two outermost sts in each gusset section will be worked as part of the legs.
Place each set of 8 [12, 12, 12, 12, 12, 16] gusset sts on waste yarn. This will separate the leg sts naturally for you. Remove the center markers.
89 [99, 111, 123, 135, 147, 157] sts in each leg
8 [12, 12, 12, 12, 12, 16] sts in each crotch gusset section
Place one leg on your 16”/40cm long circular needle. Place the other leg’s sts on waste yarn or st holder, keeping the marker in place to indicate the side seam.
Join to work in the round. You should already have a marker in place to mark the end of round.
If you have not cut your yarn, your round starts at the outside edge of the leg. You should start your second leg at this point too.
Round 1: K to inside of leg, PM between two halves of leg where the gusset was before. Pick up and knit all wraps as you get to them.
To avoid a gap where you close up the leg, cross the st before and after the st marker before placing the marker.
Continue knitting to end of round.
