The below information and images are taken from the first part of the student website evidencing the stages of sketching out Design Ideas for the Resin poured table lamp project. Some parts have been omitted to show you the main stages, however at the bottom of the page you can click on the button to see the whole website page from the student.
We sketch our designs out using blue pencil/lead as the blue color contrasts well against white or light-colored paper, making it easy to see the pencil marks during the sketching process. Furthermore, using blue lead will allow us to differentiate between the sketching stage and final lines or fine-lined areas (which we normally use as black fine line pens).
Architects use blue pencils as blue pencil marks may not appear in photocopies or scans, which means that when they copy a document, the blue lines will not show up, keeping the final design clean.
Template sheet
The template sheet is optional: but if you do use it then make sure you don't directly draw on the paper.
You'll be given a marker paper to place on top of the template sheet. Use paperclips to clip the template sheet and your marker paper together so that they won't shift when you move them around to draw at better angles (don't move your body whilst drawing. Instead, move the paper so that you're more comfortable, it'll be easier for you to draw when you are in a comfortable position). Sketch out the guidelines using blue pencil on marker paper. Your guidelines should be really light.
*Later on the teacher will be scanning our work. If the guidelines are drawn lightly, it won't appear on the scan.*
Sketching out your design lightly/ using ghost lines
Ghost lines is when you're drawing without the pencil led actually touching the paper or when you're drawing your lines really lightly.
Use your inspiration photos to think of ideas for your designs and sketch them out lightly over the guidelines you have drawn. Do not do scratchy lines when drawing out your design; draw the line in one go, if it doesn't looks the way you want it to then go over it again. Don't worry if you made a mistake or drew something you don't think looks good, because after you've finished sketching you'll need to go over them in darker lines. By that time you won't be able to see the mistake anymore as it won't stand out.
Going over your design with lines with more depth and weight
By doing this it'll allow your design to have more depth and it also makes your sketches look better. To do this you just need to squeeze the end part of your pencil (to get a darker line) and then release it (to get a lighter line), you don't need to press hard onto the paper at all (another reason not to do that is that the led is pretty easy to snap).
Any mistakes you made while sketching in ghost lines won't be visible anymore as it doesn't stands out/isn't really visible beside the darker lines.
(Don't forget to draw the wire too)
Details
For the details all you need to do is shade in the parts that is wood or just to give the design more volume and dimension. Also to show where if something is overlapping. There are many was to shade your design. I used a mix of cross hatching and just lightly coloring in.
In this design, I thought that the lamp's head looked quite plain so I decided to add something extra to the head.
Fine line pen and rendering was added to the blue pencil sketching.
Material textures were added to the rendering
Some clever 'trickery' in Procreate placed the sketch sheet onto a photo of a sketchbook
