First you want to open a new document in SolidWorks.
Now you want to double click PART.
Now that you're in SolidWorks you want to click on front view.
If you're not already in sketch mode press the sketch button in the upper left hand corner. After that you want to press the line button.
You will want to draw a line.
Make sure that all of the lines are the same length and would seem the measurements of a twig.
Now add a line for where you want the curve of your twig to go.
Now connect and proceed.
You will want to press on the 3D-arc to enhance the curve.
Once you've pressed the 3D-arc button you will want to make a curve at the tip.
Now press 3D-arc again so that you can make a slight curve on the bottom.
Adjust the curve that you would like.
Now that you have everything to your needs, you will want to extrude. So press the extrude button.
Make sure that you don't make the twig to thick... because no one likes a thick twig.
This is what my twig looks like.
