I bought all the sizes and so far have used the 1.5" one. I am very disappointed. I seems to take so much longer and still does not insure perfect meeting of lines. I may be doing something wroing - but can't figure out what.
By the time you sew all the lines, then cut all the solid lines - it seems to me you could have just make the number of cuts needed to make the 8 ( using 2 pieces of fabric ). I wrote to the company and to Shabby Fabrics - asking what they say as what the benefit is and never received an answer.

I like using this method for HST - I think they are faster and more accurate - but each person has to do what works for them!
