Video I referenced is How to Make a Linocut Look with Adobe Illustrator
But I'm not getting same result as they got. I'm Using Adobe CC 2018 Version.
After Some workaround I able to do it properly.
Points I followed:
1) Grabbed Pen Tool and Draw Two Lines 2) Select Both and Apply Stroke & Variable Width Profile 1 3) Used Blend Tool by clicking From Line-1 To Line-2
It's Simple Solution that I was Not Able to know why it's not working when giving Strokes to both lines Separately.
Here is Workaround I Did..
If you noticed in Problem I was not able to blend properly as i selected both stroke Separately , Which later i solved in Solution I'm Not sure it's bug or workaround but this helped me
