This is a dyneema wallet with a RF blocking liner and a magnetic closure. Fits USD bills and up to 5 cards on each side.
The magnetic closure is extremely satisfying and I haven't had any issues with demagnetization of credit cards. With small seam allowances, It can reasonably fit 5 cards on each side. I use it with 4 on one side and 5 on the other. Final dimensions should be about 7.75 inches by 2.8 inches when laying opened flat.
Here are the patterns I made for reference: https://design.cricut.com/landing/project-detail/633f7ba4086240c89c63630a https://design.cricut.com/landing/project-detail/634cf116f7307f07db55b0be https://design.cricut.com/landing/project-detail/634cf2170e7e3131749bdd7b
If using a cricut to cut DCF, I found that the fine point blade and scoring pen work well enough. I used 5oz DCF for the outer piece and 2.9oz DCF for the inner piece.
1. Cut pieces 2. Attach ripstop copper nickel fabric lining to the outer piece 3. Attach the inner and outer pieces with a seam allowance smaller than 1/8in if possible. Definitely not larger than 1/8in. 4. When sewing down the bottom portion of the inner piece to the outer piece, use a slightly larger than 1/4in seam allowance. The magnets will slide into that seam allowance. 5. Now that the top and bottom of the inner piece is attached to the outer piece, check that the magnets can fit inside the slightly larger than 1/4in seam allowance. If they can, then measure 1.75in from the edge on both sides and run 2-3 stitches vertically in the seam allowance. This is to keep the magnets in position. I found it easier to use the wheel on my sewing machine to manually do these really short stitches. 6. Put the magnets in and make sure to test that they are in the correct orientation so that they will keep the wallet closed 7. Sew the side edges of the inner and outer piece together 8. cleanup and use a lighter to lightly seal edges and any fraying thread.
