Make a line drawing of a building seen corner-on. Use every possible or horizontal reference to ensure that receding lines are drawn at the correct angles. … You will have many vanishing points and will discover most of them will be off the paper.
Over Easter we had a family break in North Yorkshire to celebrate our Ruby Wedding anniversary. The accommodation was two large farm houses and assorted converted farm buildings. We had an enjoyable meal together in one of the houses, Laskill Country House which was run by the daughter.
While we stayed in one of the cottages, our grown up children stayed in Laskill Grange run by the mother. This was a five minute sketch drawn with the side of the charcoal stick. This is a technique I have learned quite recently and am enjoying especially with life drawing. This is the first time I’ve used it for a building.
The accommodation was about four miles north of Rievaulx Abbey. While this was meant as a ‘quick charcoal sketch’ it took almost an hour because of the amount of detail.
I have not tried drawing lines to check for vanishing points for any of these sketches.
