To draw a Bubble Letter b, start by sketching a simple lowercase "b" as your
base. Then, outline this "b" with a thicker, rounded line to give it a bubble-like appearance. Make sure the
vertical line and the loop of the "b" are smooth and rounded. Erase the inner guidelines of the original "b"
so that only the bubble outline remains. Finally, add shading and color to enhance the three-dimensional look
of your Bubble Letter b.
