Relia-robot

Through the eye of a needle, you found a pocket reality where the ground was made of fabric - green felt hills, brown silk banks along the river, rocks made of grey velour, and so on. The river's water tasted a bit peculiar, by the nature of what it ran across, but was certainly water, and clean; the plants somehow grew as if the fabric were soil, as well, and you found it trivial to grow a burgeoning garden, and to gather wood to build a place to stay - a lean-to first, but then a cottage, and finally a proper house, with glass brought from the outside for the windows so that you could admire your wild green gardens.
