I've got two silks that are not quite equal. One of two silks is square and the second one is almost
rectangular. Sometimes when you work with one silk only it's shape doesn't really matter so much.
But when you make, for example, one square silk dissappear and then you do appear not square but
rectangular silk instead, that's not quite good I think. That's why I give them only 4 of 5 stars.
The quality of silks are quite good, no holes, no spare threads etc.
