Quilting Woes

Friday I bought some Pellon fusible quilter's grid with preprinted 1" squares for the challenge quilt I'm working on. I thought it would be easier to use than sewing oodles of squares together by the pair because you iron your fabric squares to the grid then sew the seems

I asked for 4 yards, paid and left the store. I didn't touch it again until Sunday at 7:00 pm. I opened the bag to a piece of 3 yards. The store closed at 6:00.

Last night I took it back to get the right sized piece. I was waited on by the cutting clerk. Her nametag read "Joy." I should have known right then to come back later.

She took for-ev-er to measure my original 3 yards, then cut another 4 yard piece for me. I was trying to hurry because my husband and son were waiting in the car. I unrolled the bolt for her in attempt to help speed things up. "Don't do that, I can't cut that way." She wrapped it back up on the cardboard and did it her way. I asked her for an extra inch because I was going to cut it half for two 2 yard pieces and I needed every bit of those 72 inches. It was as if I had asked for the rest of bolt for free. "I'll have to charge you for it." Aye yi yi. I'm thinking my original piece was 3 yards and a few extra inches cut in this very same store, why can't you give me ONE extra inch?

I get back to the car and apologize for taking so long and get home. I cut the 4 yard piece in half and start to lay out my fabric squares. They are 4" squares. The preprinted 1-inch grid squares aren't; there is about a 1/4" difference between the grid and the edge of my fabric, and, yes, I measured my squares again.

Now I'm going to have to adjust the way I lay out my square and the way I sew them up. And I don't know how to do that without messing up the whole project.
