I can sort of explain :S I made i circle one instead of a square
1) First of all i decided to use a dinner plate to measure the top and bottom, i cut out four circles instead of two for the extra support. Its easier to draw your circles on the fleece and dont cut to the line so when you sew youve got more room.
2) Next i measured the the circles circumfrence and then drawn a straight line on the fleece (i also doubled up on this too, to make it thicker) I decided how deep i wanted my house to be and then drawn another circle in between to make the door hole and cut out.
3) Using spare bits of fleece i made the parts to hang the house up with (up to you how big you want those) Then i pinned my house together and turned the right way round to get an idea of what it would look like when finished. I sewed the hanging strips in then sitching altogether but you could sew on when youve finished the house.
4) Stitch when happy, i hand stitched this because my sewing machine broke and to be honest i found it easier because i could unthread it if i made a mistake.
5) I also hand stitched the circumfrence of the door hole with a thin peice of fleece to make it look neat and i also made a pillow for inside.
Im sorry if my instructions arent very clear, it was all guess work with me and looking at other peoples hand made houses. Heres a picture so hopefully you know what i mean. I tied my hanging parts because they they were too long
