I have never had a problem with them and have several of their kits.
I did order a kit last year from another company & the kit called for 2 blocks & gave directions. However, I did not have the right pieces to make the correct number of blocks. I noticed the picture with the borders had 3 different blocks. The company told me they knew it was a misprint, they left out the 3rd block, but said a good quilter could figure it out. They said they had corrected the pattern & would give me a corrected copy if I would buy another kit ($39.95 +sh&h).
Needless to say I was not happy & would not buy anything from them again!
