Worth doing the course? Never done one but interested in learning, was just thinking it'd be another string to my bow. thoughts?
Yup, I think they look great done well, also most can't or can't be assed to do them so you will stand out from the rest mate
Floorskills do a great course, done elsewhere but the guys at Floorskills will show you way more stuff
Learned how to do one around 1985 with RBI Europe Carpet Consultants at an advanced fitting course at Kidderminster College. Although they can look great, I never did more than a few of them on site as the stitched seam is right on the part of the bull that is walked on, and I considered that this would prematurely wear. I do a waterfall bull but attach circular section under nose with staple gun and pull riser very tight onto gripper at newel post. Think its a better job.
Next time I do one I'll take a photo and post it on here. Its a very common way of doing it around Newcastle. May be a week or two as I only fit a couple of days a week now.
