I hate to give you the bad news, but I have never heard of anyone sewing thru the rubberized letters or objects before. If you had looked at previous posts, you would have seen that many of us seasoned quilters have voiced to outline the rubberized area of a t-shirt rather than stitching thru them. When I am searching for a topic, I go to the Advance search and by replying to a few options, I am able to find previously posted information. Just consider yourself lucky that you didn't break any needles. We have all learned from our mistakes and if your friend is delighted with the quilt, that is all that really matters. I am not a big fan of using invisible thread on a t-shirt quilt because of the weight of the quilt. I have used it on wall hangings. Good Luck with your next project.
