You don't always have the time or opportunity for tedious hand-sewn repairs. In that case, iron-on patches can be perfect for a quick fix for a hole or a stain.
These iron-on patches measure
- 3x4 cm
Tips for a good result:
Although they are designed to be ironed on as they are, I recommend also sewing them if you have the option, as it will be much more durable. But you can always iron them on quickly first if needed, and then sew them on at a later date.
It's easiest on a machine since the iron-on patches are stiff, and it might be worth using a darning foot if you have one, and then disengaging the feed dogs so you can move the fabric/garment in any direction you want. Feel free to practice on a fabric scrap with a ballpoint pen drawing of a heart or star or something. The stitches don't have to be perfectly even; the most important thing is that the patch is securely attached :)
Iron-on patches are a bit stiff, so if there's a very large worn area with a small hole, I would recommend attaching a reinforcement patch to the inside of the garment first, either with machine stitching (a bit of a quilting style with stripes or squares perhaps with thread that matches the garment?) or by using a fabric scrap and fusible web, and ironing it on the inside, and then covering the hole or stain with the flower. Of course, you can also use iron-on patches to decorate clothes that don't have any damage or wear yet :)
Reinforcement on the inside of worn areas is worthwhile so you don't get a new hole right at the edge of the iron-on patch, where there will be extra stress with the hard against the thin/worn area.
