Baking bread with spelt flour, without using a bread pan
Although similar, spelt has more protein and less starch than wheat flour.

This means that it will create a great structure but won't absorb as much liquid. This would result in exactly what you saw- it was sticky from water and protein and too loose to hold its shape but baked with a good crust.

The recipes I have seen use a mixture of flours that includes spelt.

Try adding less water.
