As in the case of a letter ‘k’, sometimes satins will come together at acute angles. You might have the impulse to attempt to turn the joining column. Sometimes this will work, but there is another way: Simply keep the angle constant, and overlap the joint. The ideal situation is where you have the acute angle column being sewn before the straight one. This allows for easy (and greater depth) or overlap.
Where the part that is coming in at a steep angle will be sewn later, the joint is more difficult, but works the same. You simply have to be careful about your shape. Sometimes this is the case where turning the angle near the end can be helpful for a smooth joint.
As with right angles, the use of an underlay object can provide better coverage, and make the joint easier to accomplish.
