Jeans – make a pattern for higher back piece (NORMAL or WIDE)

NOTE! Please read “IMPORTANT to read before adapting pants” to decide what type of back suits you best.

This pattern will give you both a “NORMAL WAIST BACK” and a “WIDE WAIST BACK”. The wide waist pattern piece is made from the normal waist pattern so you have to make this first and then adapt this to a pattern piece for the wide waist back.

Normal waist

The pattern pieces are made using the design of jeans top back piece (fig. 1). Start by removing the belt loops. If they are joined to the waist band seam or you wish to keep them, unpick the bottom stitching and pin them up onto the waist band so they can be re attached later (fig. 2).

Draw tuck marks according to the placement given by the measurement sheet. Also, according to the measurments, draw a rounded top line as shown in the top three pictures below (fig. 7).

Bottom (fig. 7) left picture below shows how to create the horisontal tuck needed to alter the angle of the jeans. Create this side (horisontal) tuck by marking a segment 1 cm wide at bottom of pattern piece side tapering down to nothing at the mark of the tuck point (bottom of the drawn vertical tuck mark). This will be cut off. Compensate for this horisontal tuck by adding 1 cm at the top side of the pattern piece tapering down into nothing at the vertical tuck (top of the drawn vertical tuck mark). Reshape the upper curve.

Draw tuck marks and extended rounded top according to placement and size in measurement sheet.

Create he vertical tuck by marking a segment 1 cm wide and tapering down to nothing at the end of he tuck line. The marked vertical tuck line will be the center for this as shown in the bottom middle picture above (fig. 7). Cut out the pieces as shown in the bottom right picture above.

As shown below (fig. 8), lay the pattern pieces  on a new piece of cotton and mark the seam allowance by adding 1 cm along all edges except the centre line (the centre piece will be cut on the fold of the fabric). Mark the fabric grain and label the pieces. Cut out.
