Here is my arrow design. I put them in box. I use a ellipse or half a ellipse in box, to do the bend. I also use perspective.

The object is playing card box, i use Graph paper. orthographic drawings is on 1st paper on top. The technique I use on 1st peper is connect lines with a point on Graph paper. On 2nd page i use The pre-existing line, then use a Perspective line. I number the drawing i did 1st.

The object is a hand sanitizer bottle. I did the orthographic drawings on top. I number each drawing i did 1st. Drawing 1& 2 i try 1st. I see that the proportions was not right. I think i did 3,4,5,6 right. I try Another view i think number 7 is not right, im not sure. I did another view, i number 8, i think i did not draw it good, i did #9, i think #9 is more better.

Here is a blob ,I use to make a magnifying glass. I make the blob, then put it in box, then i use the middle line to divide The handle from the glass. I draw circles from the box .

I try out Hexagon 1. I did not make a full box. I use quadrilateral. The non color Hexagon from top to bottom. I make the shape on a quadrilateral go down, go side to side. The Hexagon with color is down to up, I make the shape on a quadrilateral go up, go side to side. Because i did not use full box. I had to figure out how far the other end is. Green for height, purple for inbetween, blue for depth.

Non color ones, is the ones i was figure it out. The ones with color is the ones i think i got right.

I did the table, it took me time to figure it out. When i turn the table, i had issue on the size & putting it right place. I think i did it right.

Here is me expirementing with paper, i start experimenting on the right paper. The box on the paper was smaller aka cut in half. So i put 2 box's together. Then i move to the left paper, i made a box, i Experiment with the big box i draw. I got idea's from drawing different boxes, i see i could make a house & make letters. I made the letter N 2 times,i color 1 of the N. I move to right paper draw 2 houses, i color 1 of the houses. Sometimes,it can get confusing. I enjoy it
