I'm the first to admit just one of these standing by itself doesn't look like much, but when you plant 3 million 4 hundred quadzillion of 'em in a field together then they start to look like something (there are about 350 on that tobacco farm between the two fields).These things are called pinwheels or starflakes depending on the manufacturer and are available thru craft shops.There are 500 in a bag for about $3. The size I used is 10 mm. Because the "leaves" are up & down instead of left to right (not really noticable to the naked or semi-clothed eye in N-scale) I'm not sure how they would look in a bigger scale(would go with 18 mm in HO). Four of these will give you about a 6 ft. plant. I used a 1 inch by #19 brad for the "stalk", although small finishing nails would probably work O.K. also.After assembly spray paint a dark flat green (these things come in all colors but even the green ones are to light colored and shiny). AFTER you have planted the field dry brush the sides of the plants that are facing the front of the layout with a med. then a light green. Follow up with a very few plants being dry brushed slighty with a med. and dark brown.THIS CAN EASILY BE OVERDONE! If you do overdo it the field will look polka-dotted. Yes I had to much free time (need to get myself a hobby).Actually it only took about 2 hours to do both fields from start to finish.
