What do you actually need when you are starting out in manual Jewellery Illustration?
I'm a big believer in using and making the most of what you have. Not blaming the tools but learning to master the tools you have access to. Don't get me wrong, I currently have an extensive selection of art supplies but I have mindfully added to my collection over the past 19 years. When I started I purchased a a small selection of drawing tools and learnt to use that small selection.
There is is a quote by Arthur Ashe that sums this up perfectly.
"Start where you are, use what you have and do what you can."
You don't need a massive budget to spend on supplies at the beginning. If all you have is a lead pencil then sharpen it and start drawing. Learn to use that lead pencil in everyway physically possible and master that lead pencil. My illustration tutoring with Jewellers often centres around learning to use the basics ( a packet of coloured pencils, ruler and a mechanical pen) A jeweller or designer doesn't always require a high end illustration to communicate design details to their clients.
But, If you are looking to move on from your lead pencil and purchase some additional drawing tools then here is what I recommend purchasing/using if you are just starting out with Jewellery illustration.
A mechanical pencil with 0.30mm size lead or a mechanical pencil with 2mm lead and a relevant sharpener to keep it nice and sharp.
Erasers, a 2mm mechanical eraser is great for small details but a larger option is also recommended.
A ruler and or set squares (45 and 90 degree).
Paper or card to draw on. (Depending on referred drawing mediums)
A pack of coloured pencils.
Templates. Round and oval templates as well as gemstone shaped templates can help when drawing designs. (I love using Timely Templates - Diamonds and gemstones)
White gouache and a small tipped brush size 00 or 000 is recommended (and something to put the paint on like a plate or recycled lid - I use a white perspex off cut)
While there is a lot more you can use, add as you go and as you grow in confidence. Start with the basics, you don't need everything at once. Master what you do have before you add too much because having a full stationary / art supply draw can sometimes be overwhelming and unnecessary.
