Steps

Step 1 ：Translate the problem into an equation: \(\frac{{\text{{original number of stamps}}}}{2} + 5 = 22\)

Step 2 ：Subtract 5 from both sides of the equation: \(\frac{{\text{{original number of stamps}}}}{2} = 17\)

Step 3 ：Multiply both sides of the equation by 2 to solve for the original number of stamps: \(\text{{original number of stamps}} = 34\)

Step 4 ：Final Answer: Kristin started with \(\boxed{34}\) stamps.
