@alex_9456 I am sorry! I should have made it more clear with what I thought, on alphas alone you can add rows or take away rows ( that's what I meant by "edit" but I should have chosen better wordings!), they are very flexible with all that you can do with them! I hope this helps!
@alex_9456@peanutsv How long a pattern is, depends on the material you are using and how tight your knots are. To figure out how long 70 rows are for you, you can take one of your other alphas you have already knotted and measure how long a certain amount of rows is to calculate how long 70 rows are. It is not possible to edit patterns that are already posted to the website.
