my veil was super simple! first i figured out how i was going to wear it and how long/where i wanted it to fall to. i used tulle (a fine netting, i think it was 60 inches wide - i wanted it very full). i bought some clear plastic hair combs (so they wouldn't show) you could use a decorative comb, head band, whatever catches your eye! i folded the tulle, giving me a bit of genourous length on both ends ( i had bought 6 yards) I wore mine very long, a chapel length veil and a front veil that came to my elbows. at the folded edge, i took clear thread/fishline and just sewed it super loose the whole length. i then knotted the end to the tulle, and pulled it tight to gather the material until it was the same width as the plastic comb. then i took the thread and just sewed it to the comb by going around the top and between the teeth of the comb. super simple!
to get it the right length i pulled my hair to the approximate hight.placed the comb and checked the length, carefully trimming until i was happy.
you can do all sorts to jazz it up, adding lace to the edges or scarted around, adding beads, or really any trim you can think of! i spent less than $15 US on it total. here in the states, i would have had to pay probably at least 4 times that or more.
