I haven't done one of these in a long time and this one looked fun. Feel free to play along and don't forget to let me know so I can go see how bad a quilter you are too. :-)
I found this at The View from Here too which is a new-to-me blog. I enjoyed reading her archives. Not a lot of quilty content but a pleasant read. I'll visit again.
The items which apply to me are in bold italics.
Made a quilt with no knowledge, no skills, and no understanding that either are needed
Created an abomination and (at the time) was proud of it
Created a quilt that was so hideous it made people or animals go blind
Had relatives throw a quilt you made outside in the muddy yard for the dogs to chew
Used severely mismatched fabric weights when piecing, for example, heavyweight denim and lightweight cotton
Didn’t pre-wash fabrics and later had them bleed all over the finished quilt
Used badly mismatched needle and bobbin thread
Polyester fabrics that pilled (mine didn't pill)
Thick, scratchy polyester double knit fabrics
Batting that bearded up through the fabric
Free-motion quilting whose stitch size changed radically from stitch to stitch
Huge bird’s nests of bobbin thread that clogged the throat plate of the machine and broke the needle
Cluelessly attempted to stitch with a broken needle for several moments, thus perforating the quilt
Made stitches big enough to put your big toe through
Quilting lines that were about 6″ apart and allowed the stuffing to migrate and bunch up
Finished quilts that weren’t “square” and/or were badly blocked
Quilt tops that wouldn’t lay flat, that had a “volcano” in the middle or perceptible ripple
Backing that bunched up while quilting, leaving a portion of the batting uncovered
Hand-tied a quilt with heavy crochet or regular yarn, which required a really huge-eyed needle which left giant holes in the quilt
Erroneously equated a quilt with a blanket, and “finished” the edge of the quilt with a blanket stitch using scratchy acrylic yarn.
Had to use pliers to force the needle through the quilt, yet didn’t understand that this might be a sign that something was fundamentally wrong
Backed with a 100 thread count bed sheet. (Extra points for polyester)
Quilted with fishing line
Bled/sneezed/spilled coffee (iced tea) on a large section of quilt while making it.
Had people compare your quilt to one they saw at Wal-Mart
Finished a quilt (top) and only then realised that you hated it
Gave a quilt to someone and had them be speechless - and not in a good way
Trimmed loose threads on a gift quilt at the last minute and cut a hole through the top
Sewed one or more fingers to the quilt, then had to carry the sewing machine and quilt around the house while looking for a screwdriver to remove the needle
Created appliqués with satin-stitched edges, which after a shamefully brief time became frayed-edge appliqués that flapped their way free of the quilt
Oh dear! in reading back over this it doesn't sound like I'm a very good quilter does it! At least some of those go back 35 years and I can plead much improvement in the meantime! But sadly some are very recent so I have a loooooooong way to go to perfection. But I'm having fun!!!
