Let’s have another example with cubic and quadratic beziers.

Here the bottom of this bell is defined with straight lines.

<svg width="200px" height="200px" viewBox="-100 -100 200 200">
  <path fill="#FDEA96" stroke="black" stroke-width="2" d="
      M-50,40
      L-50,50
      L50,50
      L50,40"
  />
</svg>

Then a quadratic Béziers starts the bell cloak.

<svg width="200px" height="200px" viewBox="-100 -100 200 200">
  <path fill="#FDEA96" stroke="black" stroke-width="2" d="
      M-50,40
      L-50,50
      L50,50
      L50,40
      Q40,40,40,10"
  />
</svg>

Then the line is continued with a cubic Bézier to form the top of the bell.

<svg width="200px" height="200px" viewBox="-100 -100 200 200">
  <path fill="#FDEA96" stroke="black" stroke-width="2" d="
      M-50,40
      L-50,50
      L50,50
      L50,40
      Q40,40,40,10
      C40,-60,-40,-60,-40,10"
  />
</svg>

Then we reach the bottom part with another quadratic bezier that mirrors the previous one.

<svg width="200px" height="200px" viewBox="-100 -100 200 200">
  <path fill="#FDEA96" stroke="black" stroke-width="2" d="
      M-50,40
      L-50,50
      L50,50
      L50,40
      Q40,40,40,10
      C40,-60,-40,-60,-40,10
      Q-40,40,-50,40"
  />
</svg>

We finish the bell, by adding two circles for the bell-clapper, and the hanger.

<svg width="200px" height="200px" viewBox="-100 -100 200 200">
  <g stroke="black" stroke-width="2">
    <circle cx="0" cy="-45" r="7" fill="#4F6D7A" />
    <circle cx="0" cy="50" r="10" fill="#F79257" />
    <path fill="#FDEA96" d="
        M-50,40
        L-50,50
        L50,50
        L50,40
        Q40,40,40,10
        C40,-60,-40,-60,-40,10
        Q-40,40,-50,40"
    />
  </g>
