I made a doll bunk bed for Addison's birthday. It fits her dolls nicely.
I made the frame from a plan online which I roughly.followed. The wood.is about a half.inch by 1.5 inches, and cost about us$2 for all of it. It's not.the highest quality wood, but that's almost impossible to find here anyway. I sanded each piece with my angle grinder first, which actually took longer than expected. I had to work on it when Addison was home, so she did peek and spoil the surprise some. I filled the gaps with wood filler and covered the screw heads, so it's mostly smooth. Then I painted it and sewed two thin mattresses. A lot of work, but we could never buy anything close to this in our town, or even in KL.
