Persea Harem Jumpsuit

Made a few adjustments to get the look I wanted which included lengthening the leg and taking it in to be tapered. Absolutely love this pattern. Super easy and fast sew. Definitely recommend.

The Scilla Jumpsuit

Purchased this pattern to make a quilted jacket. I have not had a chance to make up the jacket yet but have read over the instructions and they are clear and easy to understand. There are a couple of variations so I will be able to make some fun jackets without them being all exactly the same. The download was flawless and printed perfectly. Would definitely recommend the pattern/designer.

It’s a lovely design. My mother is making it up, because I can’t knit to save my life. She’s fascinated by the way it’s worked up.

A zip-free Back Wrap Dress with a ruffle

Back in the Spring of 2022 I started working on sewing a dress I could wear on my upcoming holiday in Spain. So I set to work to create a dress pattern, and as usual, without fussy fasteners or zips. This blog post tells the story of how the dress came to be, what inspired it, and what pattern testers had to say about it. You can purchase the pattern as an instantly downloadable digital file from the Etsy store, to print at home or have printed via a copy shop.
